Carbon dioxide efferevensence is produced <br /> <br /> Sulphate ions <br /> Add nitric acid and barium nitrate <br /> Barium sulphate produced white ppt<br /> (bullshit) B.S<br /> <br /> Chloride ions (A.C)<br /> <br /> Nitrate ions<br /> Acid and sodium hydroxide and warm with aluminum . Ammonia gas produced . Pungent and turns moist red Litmus paper blue<br /> <br /> Iodide ions<br /> Add lead nitrate <br /> Forms lead iodide (yellow ppt) Informative Bloggerhttp://www.blogger.com/profile/11333591069184796105noreply@blogger.com0tag:blogger.com,1999:blog-4609731309991369987.post-70210213508451054272011-04-24T00:51:00.000-07:002011-04-24T04:03:39.638-07:00Defination<br /> <br /> Cations are metal ions<br /> <br /> They can be identified by adding <br /> 2 reagents<br /> Calcium Hydroxide, Ca(OH)2<br /> Aqueous Ammonia. , NH3<br /> <br /> O level syllubus<br /> <br /> when ions react with sodium hydroxide/aqueous ammonia<br /> coloured compounds or white compounds are formed <br /> <br /> Coloured coumpounds : <br /> Copper (2) ions<br /> Iron (2) ions <br /> Iron (3) ions<br /> <br /> white ppt compounds <br /> calcium ions <br /> lead ions <br /> aluminium ions <br /> zinc ions <br /> <br /> Colourless coumpounds <br /> ammonium ions<br /> <br /> <br /> <br /> All win method !!!!!<br /> <br /> Ions. Add Sodium hyroxide/Aqueous Ammonia <br /> Copper. Blue ppt(copper hydroxide is formed)why blue ?Cu(u is part of blue)<br /> Iron(2). Green ppt (iron hydroxide is formed)why green ? Green (ee) is charge 2<br /> iron(3). Red ppt (iron hydroxide is formed) why red ? ( red is 3 letters charge 3 )<br /> <br /> white is a human nature = LAZy Cow<br /> <br /> L= lead<br /> A= aluminium<br /> Z= zinc <br /> <br /> C= calicum <br /> <br /> <br /> <br /> <br /> how do u all win ?Informative Bloggerhttp://www.blogger.com/profile/11333591069184796105noreply@blogger.com0
