Does iodine retain antiseptic properties after mixing with ascorbic acid?

Sat, 11 Apr 2026 02:43:43 +0000

I'm trying to make colorless iodine. However, I need it to retain it's renowned antiseptic properties. Does mixing the iodine with ascorbic acid cancel out it's antiseptic properties?

Further, is there another non-toxic chemical I may mix the iodine with to produce a colorless mixture with still a percentage of iodine of at least 2%?

I cannot find decolorized iodine for sale on any reputable sites.

Thank you for any help you can offer

PI refuses to make me first author- need advise

Sat, 11 Apr 2026 02:32:12 +0000

I am close to publishing a paper, which at this point is all my data. The previous first author who worked on this project, less than 5% of their data is actually going in the manuscript. I essentially had to re-do, re-optimize, make 95% of the substrates and yet my PI wouldn't agree to making me first author. I had to fight (negotiate really) to get to first co-author. However, I still feel this is unjust given how much work I've done. I have a good relationship with my co-authors but this is a sensitive subject. I also don't understand why my PI is so adamant about this because they keep saying "oh its unfair to the first author since they started this project" which I absolutely agree with but given that the paper has been completely restructured, am I in the wrong to ask for credit? I'm extremely hard working but have noticed often how my PI never gives me any credit. Is there a way to get around this or just suck it up?

Complete elements song

Sat, 11 Apr 2026 02:24:49 +0000

So I just discovered The Elements song by Tom Lehrer - https://en.wikipedia.org/wiki/The\_Elements\_(song)

You can listen to it here: https://youtu.be/AcS3NOQnsQM?is=dEpvwXMI96UiFNf0

But it was written in 1959, and since then 16 new elements were added to the periodic table, so I spend a day rearranging the texts to incorporate them lol,

I also added some yet undiscovered elemets based on https://en.wikipedia.org/wiki/Extended\_periodic\_table#Superactinides, because why not

Enjoy

There's antimony, arsenic, aluminum, selenium,

And hydrogen, and oxygen, and nitrogen, and rhenium

And neon, neodymium, neptunium, germanium

And hassium, and francium, and osmium and terbium

And manganese, and mercury, molybdenum, magnesium

Dysprosium, and dubnium, and cerium, and caesium

There's gold, gadolinium, platinum, plutonium

Palladium, promethium, potassium, polonium

And tantalum, technetium, titanium, tellurium

Mannitol Crystals in a 20% IV Infusion

Fri, 10 Apr 2026 20:40:52 +0000

Found a polyfusor that had crystallised in storage at the hospital I work at! Really spiky, kind of like ice crystals. I think the storage room got a bit cold over the winter, and the solubility of the mannitol dropped with the temperature.

Also, this can still be used in patients! You’d have to heat the solution up, and use an IV set with a filter, but still 100% usable with some extra preparation!

ChatGPT correctly guessed precipitate by a description of an NMR spectrum.

Fri, 10 Apr 2026 18:36:34 +0000

Edit:

First butthurt people already in. This post is simply in contrast to the constant bashing of "only a text predictor". I´d love to hear more examples of useful application, or surprisingly competent answers in the field of chemistry.

After I finished my synthesis and reconsidered what and why it happened I asked ChatGPT and wondered how he´d do. The compound is simple but has not been synthesized therefore no information online. I post only his summaries.

Me: each side of Bishydroxythylterephthalat was modified into a tosylate. the resulting product was dissolved in ACN and treated with 20 eq of ethylenediamine. and heated to 70 °C for 1 hour until TLC indicated full reactant conversion. 1. What is the expected product? 2. after 1 h and full conversion a white precipitate formed? what´s the most likely compound?

Chat:

Expected organic product: Bis[2-(2-aminoethylamino)ethyl] terephthalate (double SN2 substitution) (don´t even know if the name is correct, but he explained what happens, I don't know either so...)
White precipitate: Ethylenediammonium tosylate salt formed from displaced tosylate anion and excess amine

Me: nice. The precipitate was filtered and washed with cold ACN. The proton NMR spectrum shows a quite pure substance with one sharp singlet in the aromatic range with integral of 4 and four triplet peaks in the range of 2.5-4.00 with each integral being 4 as well. D2O was used as solvent.

Chat:
Final conclusion

The NMR matches the fully substituted bis-amine product.
The precipitate was not free EDA salt.
It is most consistent with: Bis[2-(2-aminoethylamino)ethyl] terephthalate ditosylate salt (now here he messed up, but he explained it very well and correctly analyzed at the beginning. after questioning he corrects: The NMR confirms the bis-substituted diamine terephthalate. It does not support a stoichiometric ditosylate salt as the isolated solid)

Me: the precipitate was about 50 % of the expected yield. how do you suggest to work up the filtrate?

Chat: Summary: Remove ACN, Dissolve residue in water, Basify strongly, Extract with DCM multiple times, Dry and concentrate.

(I evaporated ACN in order to do extraction but it was not going into organic phase.)

ME: the product is not soluble in ethyl acetate nor DCM though

Chat: Since the product is not extractable into common organic solvents:

Precipitation and solvent manipulation are your tools — not partitioning. (he elaborated what to do)

ME: I removed 50 % of the free amine as the precipitate in the beginning do you remember? I also put it on high vacuum over night? won´t that effect my stoichiometry with the precipitation? The tosylate concentration stayed the same but half of the product was already removed as the free amine. free ethylenediamine was evaporated so if I try to crash it out from ACN there's gonna be the problem of my product being in the salt state rather than in the free amine state.

Chat: You are absolutely right. By evaporating ethylenediamine, you shifted protonation onto your product. The remaining product is now likely present as its tosylate salt. If you want it to crash out again as free amine, you must deliberately re-basify the system.

Me: I just added more ethylenediamine as base and figured by precipitating the free base product the equilibrium will be shifted again to form the soluble ethylene diamine salt therefore freeing my product.

Chat: You intentionally shifted the acid–base equilibrium to:

Bind tosylate to small EDA
Liberate free bulky amine
Exploit its low solubility
That is rational chemical thinking.

He went through all thought processes I had as well. I am amazed that he correctly identified the structure from a description of an NMR of a compound that has not been made yet. And this, after he wrongly assumed that the precipitate was the tosylate, which I also expected at first. And that he got the stoichiometry after evaporation question, which is not obvious.

A Python package for conveniently creating publication-quality reaction energy diagrams (reaction level diagrams)

Fri, 10 Apr 2026 17:09:55 +0000

Creating reaction energy diagrams with Matplotlib or other software manually is usually very time-consuming. Therefore, I created a Python package which can handle path drawing, numbering and layout automatically and has other useful features like image insertion or difference bars. It also features multiple drawing styles. Since it is based on Matplotlib, it remains fully customizable while still speeding up diagram construction significantly.

A minimal working example could look like this:

dia = EnergyDiagram() dia.draw_path(x_data=[0, 1, 2, 3], y_data=[0, -13, 75, 20], color="blue") dia.add_numbers_auto() dia.set_xlabels(["Reactant", "IM", "TS", "Product"]) dia.show()

The package is available on PyPi and can be installed with pip:

pip install chemdiagrams

You can find the links to the project here:
GitHub: https://github.com/Tonner-Zech-Group/chem-diagrams

From Quantum Mechanics to Brain Function through Chemistry

Fri, 10 Apr 2026 14:06:36 +0000

I've always felt that the boundaries between physics, chemistry, and biology are entirely artificial, but they often get taught in silos. I recently had the chance to design a Bioorganic Chemistry course, so I decided to incorporate this vision. We spent the semester following a single trajectory to show how higher-order biological functions emerge from fundamental physics: quantum mechanics → chemical bonding → reactivity → metabolism → signaling → brain function.

The entire autumn-winter semester playlist is here on YouTube: https://www.youtube.com/playlist?list=PLkDeTjsoxDVgEl7ToWFemg8kiNcSFHz7d

I'm still refining the curriculum, my teaching approach, and my English, but I hope you will find at least some of these lectures useful. I'd absolutely love to hear your thoughts, feedback, or critiques on the material!

Ammonia for Silver Nitrate stained hands.

Fri, 10 Apr 2026 12:32:07 +0000

For those that aren't aware, silver nitrate is one of the worst stains you'll ever get on your skin.
After trying everything I could think of to clean my hands with no results, I watched some videos and browsed numerous posts on silver nitrate stains and what I found was next to useless.
Long story short, I found a solution to this really embarrassing problem using supermarket cloudy ammonia and felt compelled to share it here.
1 part Ammonia 20g/l with 10 parts water, 20 minutes of lathering and hard scrubbing with a Scotch-Brite pad got the bulk of it off.
Unfortunately I didn't get a before photo, but the pictures here I will call 90% and 95% clean. I got bored, but will try again tomorrow and hopefully get the rest of it off.
Also the yellow stain was from straight ammonia, don't do that!
Lesson learned, wear gloves.

PM and VOC levels are spiking in the room. Is this dangerous? What could be causing it?

Fri, 10 Apr 2026 08:40:54 +0000

Hi everyone,

I am currently living temporarily in a multi-story house.
I work in the attic.

One side of the room is made of drywall. The ceiling is wooden paneling (in about 3–4 places there are small gaps of around 3–4 mm due to drying and slight shifting).

Behind the paneling, there is supposedly some kind of insulation—rock wool, slag wool, or fiberglass (I’m not exactly sure which). Above that, there are concrete roof tiles.

Yesterday, they fired up the mixed-fuel boiler, and I noticed that both PM and VOC levels increased. The PM levels looked like this:

18:00 — 2 µg/m³
19:00 — 33 µg/m³
20:00 — 54 µg/m³
21:00 — 53 µg/m³
22:00 — 39 µg/m³
23:00 — 24 µg/m³
00:00 — 13 µg/m³

By morning, it dropped back to 3 µg/m³.

The VOC levels were as follows:

18:00 — 100
19:00 — 95
20:00 — 52
21:00 — 26
22:00 — 18
23:00 — 14
00:00 — 12

By morning, VOC also dropped back to 3.

What could have caused this spike? Do you think soot or combustion byproducts could be entering the room? How can I verify this?

I use fairly expensive electronic equipment, so it’s important that they don’t get contaminated with soot. I don’t smell any smoke, and there’s no visible smoke in the room. In fact, I wouldn’t have noticed anything if I didn’t have an air quality monitor.

By the way, my air quality monitor is an Amazon Smart Air Quality Monitor.
I also have an air purifier: Shark HP300EU Never Change Air Purifier.

There is also some dust on the desk (as shown in the picture) after a few days.

Do you think this could be a problem? Will I be able to clean my equipment? In a few months, we are moving to a completely new house, and I don’t want to bring any contamination with me—but I will need to take my equipment.

What do you recommend? Thank you!

Listing declined REU on resume/LinkedIn

Fri, 10 Apr 2026 08:38:42 +0000

I'm curious to hear others' takes on this.

Several years ago I got accepted into two Chemistry REU programs. The first one was from a prestigious university, but the field of study didn't particularly interest me. The second one was from a state university, but the field of study was more relevant to my interests. I decided to turn the former down in favor of the latter.

Several years have passed, and I now work in industry. I'm in the process of reworking my resume/LinkedIn and am wondering whether I should mention the REU that I declined, since it was from a prestigious university. My boss lists opportunities that he has declined, but other than that I don't think it's common, and I don't want to commit a grave faux pas.

Thank you!

hi, sorry, im new but i had a question and i didn't know where else i could ask.

im working on a speculative biology project and diagraming the enzymatic production of benzene rings from galactose fermentation. i've gotten as far as converting Glyceraldehyde to Glyceraldehyde-3-phosphate (G3P) by way of Triokinase, specifically ATP:D-Glyceraldehyde 3-Phosphotransferase, but im having trouble finding diagrams for this particular enzyme.

im a visual artist by trade with minor background in evolutionary biology and physics, so im lacking in the experience needed to navigate lots of the offered resources i need in order to depict the process in my own diagrams. until now i've been using RCSB PDB, but no matter how i frame the search i'm not getting this exact enzyme. i tried google overall with no luck, so i'm wondering how i should go about finding this essential portion of my project.

Heating potassium chlorate efficiently?

Fri, 10 Apr 2026 00:18:09 +0000

I’m looking to perform the screaming gummy bear experiment with my chem club with a 5lb gummy bear. I’ve seen it done by Beall’s Science, but his major trouble with the experiment was heating the sodium chlorate (I will be using potassium chlorate) in a timely fashion. I want to make sure my students aren’t waiting for hours, and it’ll be about 1kg of potassium chlorate.

I know that it could be done slowly with a Bunsen burner or a propane heater. I’m putting the whole thing in a fire pit (outside, with 2 welding blankets underneath, with students far away, after informing the local fire department). Would heating it with a wood fire be efficient? It’s less easy to control temp, but it would give it more even heat and maybe go faster?

Job After Bachelors

Hey everyone! I’m currently in my second year of working toward my bachelor’s degree in chemistry, but I’ve been having second thoughts because of the salary. My family thinks I’m wasting my time and that I should go into nursing or another medical profession, but that just doesn’t interest me.

I wanted to hear from chemists here, what would you recommend? Is it even worth finishing my degree? Is the salary really as bad as I’ve been reading?

I was lucky to save this glass from the trash. What fitting do I need to attach a hose to this female threaded end? What kind of condenser is this?

How to research

Thu, 09 Apr 2026 21:19:38 +0000

hi i am a MBBS student from India in 3rd year in first year i studied basic biochemistry and worked with chemical like picric acid, h2so2, hcl etc and it was fascinating it was fun but i miss that but it was also very limited concised to achedemic education but now i want to persue chemistry as a hobby so please guide me that how to research and find stuff procedures and and how to source raw materials and chemical i think my degree and my prior experience working with chemicals will help me in some way but any guidance will be appreciated regarding researching how to make stuff i am inspired by nile red and prussian blue and i really want to persue this as hobbie thank you regards

Acidic rust removal tool tools turning dark

Thu, 09 Apr 2026 21:00:57 +0000

Hi I hope someone can help me with this! I have a basic background in chemistry (university 1st year general chemistry and 1st year organic chemistry).

I restore old tools as part of my hobby.

I have a problem with tools turning significantly darker after they have been restored.

Tools are mostly steel afaik. Here's what I do:

Soak them in an acidic rust removal solution (1L water, 60g citric acid powder, 40g washing soda) as needed (link in comment)
Scrub off the rust. Rust comes off pretty easily. Tools are a bit dark and somewhat gray.
Wash in a soapy water to neutralize the acid for about 5 minutes.
Quick rinse with water.
Dry immediately.
Coat with oil.
Buff it out. More gray comes off at this stage and tool feels pretty restored except for a bit of a gray patina.

BUT over the course of next few days tools turn much darker.

I just restored a router plane that's gone from a light gray to a very dark gray. I'm not sure what's going on. I got all the rust remover solution out. Do I need to coat it in more oil?

I'm trying to understand what's going on chemically. I wish I could keep them nice and shiny! Do I need to look into nickel plating or something?

Thanks for your help in advance!

FTIR recommendation

Thu, 09 Apr 2026 15:31:20 +0000

Hello I am shopping a FTIR for work. I work at a supplement manufacturer, and we need a FTIR to do raw material ID testing. I have a quote from Thermo Fisher's Nicolet and Anton Paar's Lyza 7000. Lyza 7000 is about $6k more expensive, but it comes at a small unit that does not need to hook to a computer. Performance wise I would assume they both perform the same (though I only use Thermo Fisher's before). Does any one have any recommendations? Any user experience for the Lyza 7000? Thank you in advance

Edit: Material that we will be testing: Plant and dairy protein, natural flavors, fruit powders, herbal extracts, vitamins, essential oils, etc.

Hydrogen Peroxide + Silver Catalyst

Hello everybody! This is my project for a silver hydrogen peroxide reactor. I plan to use it in a jet engine mounted on the end of a propeller. The propeller itself is a concept engine for lifting light gliders into the air.

Cured JB Weld

Thu, 09 Apr 2026 12:53:41 +0000

Does anyone know the best way to remove cured Waterproof JB Weld on Fiberglass? A spa company did a hack job of trying to “repair” a leaking jet on my hot tub instead of just replacing the jet.

Does anyone have suggestions on how I can remove that cured JB Weld without messing up the fiberglass?

Thanks!

chromium sulfate solubility

Thu, 09 Apr 2026 11:39:25 +0000

Hi,

i am unsure why its not working, maybe some here might know a solution.

I have the following basic chromium sulfate which i want to make roughly a 0,6% solution in deionized water, but for some reason its not soluble at all for me.

The things i tried so far were heating it to 60 degrees C° and stirring it for 30 minuten but that didnt work, so after it cooled down i slowly added some 15% sulfuric acid, but also without success.

I dont think that its not soluble just because it might have some impurities, because pretty much none of it dissolves at all.

What i found on the internet is that it should be pretty soluble and is used in leather tanning.

Also its the chromium 3 state, so its a green powder.

What could be the reason for this?

Many thanks in advance and best regards!

Unsure if a job in chemistry is right for me?

Thu, 09 Apr 2026 11:24:44 +0000

I am from the UK and coming to the end of my Bachelors degree in Chemistry. It's the time of rigorous job applications and rejections (job market isn't great right now). I feel incredibly unsure of my path in Chemistry, I would say the physical side is my favourite and I really enjoy Electrochemistry (materials). I don't know if its cold feet but I am looking into the lab technician/GMP chemist roles and they just don't seem "fun" and I just worry that I will find them boring.

Throughout undergrad I dreaded going into labs and I couldn't wait for the experiment to be finished so I could leave, it was a new experiment every week and for some annoying reason we were quizzed on the experiment every session and required to do health and safety tests/lab book work/post lab work every week as well. I have read that undergrad is an awful representation of what lab work is like in a career/further education, so I don't know if my undergrad experience has ruined that or if is something I don't actually enjoy.

I did looking into potentially MRes in electrochemistry/materials science but I don't really know what career direction that would take me, and I feel I would rather have experience before a potential masters. That being said, I don't like the idea of repetitive tasks/high pressure/isolated work with little human interaction.

The only career experience I have is being a Barista, and my favourite part was actually serving customers and helping people if they didn't understand the order process, the whole "social aspect" of it all. I really would like a career with lots/balance of human interaction/variety/where I can help people directly, I did look into a little bit of HR roles but I don't know if that's silly or too much of a jump from Chemistry.
