&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; font-size: large;&quot;&gt;&amp;nbsp; Quando recebemos uma amostra desconhecida o primeiro passo é identificá-la. Para isso podem ser feitas diversas análises, dentre elas a identificação dos cátions.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; font-size: large;&quot;&gt;&amp;nbsp; Os cátions são divididos em cinco grupos de acordo com as &quot;propriedades reativas&quot; de cada um, ou seja, os que reagem com o mesmo tipo de substância sendo caracterizado pela formação de precipitado.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; font-size: large;&quot;&gt;&amp;nbsp;Portanto cada grupo tem um reagente específico:&lt;/span&gt;&lt;/div&gt;
&lt;b&gt;&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; font-size: large;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/b&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; font-size: large;&quot;&gt;Os cátions
deste grupo formam precipitado com HCl diluído. Os íons deste
grupo são: Pb&lt;sup&gt;+2&lt;/sup&gt;, Hg&lt;sub&gt;2&lt;/sub&gt;&lt;sup&gt;+2&amp;nbsp;&lt;/sup&gt;e Ag&lt;sup&gt;+&lt;/sup&gt;.

&lt;div class=&quot;MsoNormal&quot; style=&quot;line-height: 13.5pt; margin-bottom: 15pt; text-align: justify; text-indent: 35.4pt;&quot;&gt;
&lt;span style=&quot;font-size: large;&quot;&gt;&lt;span style=&quot;font-family: Arial, sans-serif; line-height: 115%;&quot;&gt;Os cátions deste grupo não reagem com ácido clorídrico, mas formam
precipitado com ácido Sulfídrico em meio ácido mineral diluído. Os íons desse
grupo são: Hg&lt;sup&gt;+2&lt;/sup&gt;, Bi&lt;sup&gt;+3&lt;/sup&gt;, Pb&lt;sup&gt;+2&lt;/sup&gt;, Cu&lt;sup&gt;+2&lt;/sup&gt;,
Cd&lt;sup&gt;+2&lt;/sup&gt;. Todos precipitados são pretos, exceto o CdS que é amarelo.&lt;/span&gt;&amp;nbsp;&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;

grupo não reagem nem com ácido Clorídrico nem com ácido Sulfídrico em meio
acido mineral diluído. Todavia formam precipitados com sulfeto de amônio em
meio amoniacal e fortemente eletrolítico. Os cátions deste grupo podem ser
subdivididos em 3A e 3B. Os íons do grupo 3A são: Fe&lt;sup&gt;+3&lt;/sup&gt;, Cr&lt;sup&gt;+3&lt;/sup&gt;,

claro e Al(OH)&lt;sub&gt;3&lt;/sub&gt;&amp;nbsp;branco. Os íons do grupo 3B são: Fe&lt;sup&gt;+2&lt;/sup&gt;,
Mn&lt;sup&gt;+2&lt;/sup&gt;, Zn&lt;sup&gt;+2&lt;/sup&gt;, Co&lt;sup&gt;+2&lt;/sup&gt;, Ni&lt;sup&gt;+2&lt;/sup&gt;. Todos

grupo não reagem nem com reagente do grupo I, nem do II, nem do III. Eles
formam precipitado com carbonato de amônio na presença de cloreto de amônio em
meio neutro ou levemente ácido. Os cátions desse grupo são: Ba&lt;/span&gt;&lt;sup style=&quot;font-family: Arial, sans-serif; line-height: 150%; text-indent: 35.4pt;&quot;&gt;+2&lt;/sup&gt;&lt;span style=&quot;font-family: Arial, sans-serif; line-height: 150%; text-indent: 35.4pt;&quot;&gt;, Ca&lt;/span&gt;&lt;sup style=&quot;font-family: Arial, sans-serif; line-height: 150%; text-indent: 35.4pt;&quot;&gt;+2&lt;/sup&gt;&lt;span style=&quot;font-family: Arial, sans-serif; line-height: 150%; text-indent: 35.4pt;&quot;&gt;,

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; font-size: large;&quot;&gt;&lt;span style=&quot;line-height: 115%;&quot;&gt;Os cátions deste grupo não apresentam reagente geral. São
solúveis nos precipitantes de outros grupos, fato pelo qual estão sempre em
solução. O único íon do grupo que necessita de precipitação para sua confirmação
é o magnésio, sendo que os íons sódio e potássio serão analisados pela
coloração na chama do bico de Bunsen. A análise do íon amônio será efetuada,
tirando partido da volatilização do amoníaco. Os cátions desse grupo são: Mg&lt;sup&gt;+2&lt;/sup&gt;,
K&lt;sup&gt;+&lt;/sup&gt;, Na&lt;sup&gt;+&lt;/sup&gt;, NH&lt;sub&gt;4&lt;/sub&gt;&lt;sup&gt;+&lt;/sup&gt;. Precipitados: Mg(OH)&lt;sub&gt;2&lt;/sub&gt;&amp;nbsp;azul,
K&lt;sup&gt;&amp;nbsp;&lt;/sup&gt;chama violeta, Na chama amarela, NH&lt;sub&gt;4&amp;nbsp;&lt;/sub&gt;teste
fenolftaleína.&lt;/span&gt;&amp;nbsp;&lt;/span&gt;&lt;o:p&gt;&lt;/o:p&gt;&lt;/div&gt;

&lt;span style=&quot;color: orange; font-family: Arial, Helvetica, sans-serif; font-size: large;&quot;&gt;O que são? Para que servem?&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; font-size: large;&quot;&gt;&amp;nbsp; Como o próprio nome já sugere, aditivos químicos são substâncias
adicionadas aos alimentos para torná-los mais saborosos, mais visivelmente
bonitos e até mesmo mais nutritivos, além de facilitar sua estocagem, pois
alguns deles aumentam a “validade” dos alimentos. A maior prova disso foi a
descoberta feita pelo homem pré-histórico, quando ele percebeu que se salgasse
a carne e a deixasse no sol, ela não precisaria ser consumida imediatamente,
como era feito. &lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; font-size: large;&quot;&gt;&amp;nbsp; Com o passar do tempo, foram descobertas novas formas de
aumentar a vida útil de diversos alimentos, já que antigamente o transporte dos
alimentos de onde eram produzidos – no campo – até a cidade, onde eram consumidos
demorava muito e a maioria deles acabavam estragando.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; font-size: large;&quot;&gt;&amp;nbsp; Basicamente, um aditivo é uma substância adicionada
intencionalmente ao alimento para se obter um efeito específico. Por exemplo as
vitaminas, o iodeto de potássio (que é adicionado ao sal para suprir a nossa necessidade
de iodo, prevenindo doenças), entre outros.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; font-size: large;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; font-size: large;&quot;&gt;&amp;nbsp; Segundo a função que exercem, os aditivos são agrupados da
seguinte maneira:&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; font-size: large;&quot;&gt;&amp;nbsp; Atualmente
há muitas discussões acerca dos alimentos com aditivos, se são ou não saudáveis,
entre outros. O importante é que você saiba o que está comendo e se é benéfico ou
não para o seu organismo, pois do jeito que as coisas estão indo vai ficar
cada vez mais difícil, com o passar dos anos, comer algo sem aditivos... diria
até impossível.&lt;/span&gt;&lt;/div&gt;

Por exemplo, os alótropos do elemento carbono: carbono diamante e carbono grafite diferenciam-se pela estrutura cristalina. Os alótropos do oxigênio: gás oxigênio e o gás ozônio diferenciam-se pela atomicidade. &lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;span style=&quot;color: orange;&quot;&gt;3.&lt;/span&gt; Isótopos são átomos do mesmo elemento (mesmo número atômico) que possuem números de massas diferentes. Hidrogênio, deutério e trítio são os isótopos do elemento hidrogênio. &lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;span style=&quot;color: orange;&quot;&gt;4. &lt;/span&gt;Numa ligação iônica, os íons mantêm-se unidos através de atrações eletrostáticas. Os compostos iônicos são sólidos, na temperatura ambiente, cristalinos, têm altos pontos de fusão e ebulição e conduzem a corrente elétrica quando fundidos ou em solução aquosa. &lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;span style=&quot;color: orange;&quot;&gt;5.&lt;/span&gt; A ligação covalente ocorre através de um compartilhamento de pares eletrônicos enquanto que na ligação iônica temos uma transferência de elétrons e os átomos atraem-se eletrostaticamente. &lt;br /&gt;&lt;br /&gt;&lt;span style=&quot;color: orange;&quot;&gt;&lt;br /&gt;6.&lt;/span&gt; As pontes de hidrogênio são responsáveis pelo aumento anormal do ponto de ebulição da água. Os compostos capazes de formar ligações de hidrogênio normalmente possuem maiores pontos de ebulição e menor volatilidade. &lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;span style=&quot;color: orange;&quot;&gt;7.&lt;/span&gt; Nos hidrocarbonetos quanto maior a cadeia carbônica, maior o número de interações por forças de van der Waals (forças de London), logo, maior o ponto de ebulição. &lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;span style=&quot;color: orange;&quot;&gt;8.&lt;/span&gt; Carbono quiral é o carbono saturado por quatro radicais diferentes. Por exemplo, o ácido láctico. A presença deste tipo de carbono na extrutura desencadeia a isomeria óptica. &lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;span style=&quot;color: orange;&quot;&gt;9.&lt;/span&gt; Para que uma reação ocorra, é necessário que as moléculas colidam entre si, de modo que haja quebra de ligação e formação de novas ligações. É necessário que as moléculas colidam com uma orientação favorável e com energia suficiente. A energia necessária que uma molécula deve possuir chama-se energia de ativação. O complexo ativado é o estágio de máxima energia de uma reação química.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;span style=&quot;color: orange;&quot;&gt;10. &lt;/span&gt;A energia de ativação de uma reação química é a energia que dá início ao processo. Os catalisadores atuam de forma a diminuí-la, aumentando a velocidade da reação. A faísca elétrica e a chama fornecem a energia suficiente para que as moléculas cheguem à formação do complexo ativado. &lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;span style=&quot;color: orange;&quot;&gt;11.&lt;/span&gt; A utilização de talheres de prata em alimentos contendo derivados do enxofre, como, por exemplo, ovos e cebola, escurece a prata. &lt;br /&gt;&lt;br /&gt;&lt;br /&gt;4Ag(s)+ 2H2S(g)+ O2(g) → 2Ag2S(s) + 2H2O(l)&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;Para remover a cor escura dos objetos de prata sem eliminar a superfície do metal os íons Ag+ constituintes do sulfeto de prata usamos um redutor. Envolve-se o material de prata em folha de alumínio, e em seguida mergulhamos o material em solução diluída de bicarbonato de sódio. O alumínio - redutor mais forte que a prata - é oxidado a Al+3, enquanto os íons prata são reduzidos a prata metálica, que é novamente Depositada sobre a superfície do metal sem ter havido corrosão. &lt;br /&gt;&lt;br /&gt;&lt;br /&gt;Observe a reação que ocorre:&lt;br /&gt;&lt;br /&gt;&lt;br /&gt; 2Al(s) + 3Ag2S(s) → 2Al+3 + 3S-2 + 6Ag(s) &lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;span style=&quot;color: orange;&quot;&gt;12. &lt;/span&gt;Alguns insetos podem andar sobre a água. Uma lâmina de barbear, se colocada horizontalmente, também flutua na água. Isto deve-se à tensão superficial da água: uma propriedade que faz com o líquido se comporte como se tivesse uma membrana elástica em sua superfície.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;span style=&quot;color: orange;&quot;&gt;13. &lt;/span&gt;Solubilidade dos sais: são sempre solúveis: nitratos, compostos de metais alcalinos e amônio; cloretos, brometos e iodetos (exceto os de Ag, Pb e Hg); sulfatos são solúveis, exceto os de Ba, Ca, Pb e Sr; os carbonatos e fosfatos são insolúveis, exceto do grupo 1; os sulfetos são insolúveis, exceto os dos grupos 1 e 2. &lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;span style=&quot;color: orange;&quot;&gt;14. &lt;/span&gt;Os efeitos coligativos dependem da natureza do solvente (iônico ou molecular) e do número de partículas em solução. Quanto maior o número de partículas: menor a pressão de vapor - menor o ponto de congelamento - maior o ponto de ebulição - maior a pressão osmótica. &lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;span style=&quot;color: orange;&quot;&gt;15. &lt;/span&gt;Na eletrólise e nas pilhas a oxidação ocorre no ânodo e a redução ocorre no cátodo. &lt;br /&gt;Na eletrólise os cátions (+) migram para o Cátodo (-) e os Ânions (-) migram para o Ânodo (+). Nas pilhas os sinais do cátodo e ânodo se invertem. Para determinar a ddp da pilha conserve o sinal de quem se reduz (maior valor) e inverta o sinal de quem se oxida (menor valor) e simplesmente some os dois. Se o resultado for positivo a reação é espontânea.Um mol de elétrons movimentam 96500 Coulombs de energia o que equivale a 1 Faraday.&lt;/span&gt;</content><link rel='replies' type='application/atom+xml' href='http://muitomaisquimica.blogspot.com/feeds/8663081231201187266/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://muitomaisquimica.blogspot.com/2012/07/dicas-importantes.html#comment-form' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/8327127807245707970/posts/default/8663081231201187266'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/8327127807245707970/posts/default/8663081231201187266'/><link rel='alternate' type='text/html' href='http://muitomaisquimica.blogspot.com/2012/07/dicas-importantes.html' title='Dicas importantes'/><author><name>Unknown</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='https://img1.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-8327127807245707970.post-4671693658207797815</id><published>2011-06-29T13:00:00.003-03:00</published><updated>2011-06-29T13:00:00.986-03:00</updated><category scheme="http://www.blogger.com/atom/ns#" term="efeito crioscópico"/><category scheme="http://www.blogger.com/atom/ns#" term="neve"/><title type='text'>Sal + Neve = Efeito Crioscópico</title><content type='html'>&lt;span class=&quot;Apple-style-span&quot; style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Quando se adiciona um soluto não-eletrólito e não-volátil à água pura, a temperatura de solidificação da solução diminui.&amp;nbsp;&lt;/span&gt;&lt;span class=&quot;Apple-style-span&quot; style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;O valor absoluto dessa diminuição é chamado de efeito crioscópico.&lt;/span&gt;&lt;br /&gt;
&lt;span class=&quot;Apple-style-span&quot; style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;O sal quando adicionado à neve se dissolve, ela por sua vez se funde. Isso é constatado, por exemplo, quando se adiciona cerca de 23,3% de NaCl na água, seu ponto de congelamento reduz a 21,1 °C.&lt;/span&gt;&lt;br /&gt;
&lt;span class=&quot;Apple-style-span&quot; style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Por isso em alguns países se joga sal nas ruas quando a fim de diminuir a quantidade de neve xD&lt;/span&gt;&lt;br /&gt;

O &lt;b&gt;TNT &lt;/b&gt;causa grandes estragos além de liberar muitos gases.&lt;br /&gt;
&lt;div&gt;Esse explosivo é obtido pela reação de trinitração do tolueno, sendo que a entrada dos grupos NO&lt;span class=&quot;Apple-style-span&quot; style=&quot;font-size: xx-small;&quot;&gt;2 &lt;/span&gt;se dá em &lt;i&gt;orto &lt;/i&gt;e &lt;i&gt;para&lt;/i&gt;.

A cor da chama é característica de cada elemento e permite uma primeira identificação.

&lt;br /&gt;
&lt;br /&gt;
&lt;ul&gt;&lt;li&gt;Leucipo e Demócrito&lt;/li&gt;
&lt;/ul&gt;Propuseram no século V a.C., a matéria&amp;nbsp;divisível&amp;nbsp;ate se chegar a uma&amp;nbsp;partícula&amp;nbsp;que não poderia mais ser dividida &amp;nbsp;e que seria a unidade fundamental da matéria , a qual chamamos de&amp;nbsp;átomo, seria maciço e&amp;nbsp;esférico.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;ul&gt;&lt;li&gt;Dalton&lt;/li&gt;
&lt;/ul&gt;Experimento realizado no final do&amp;nbsp;século&amp;nbsp;XVIII, retomou a teoria&amp;nbsp;atômica&amp;nbsp;e fez as seguintes&amp;nbsp;considerações:&lt;br /&gt;
&amp;nbsp;-&amp;nbsp;átomo&amp;nbsp;maciço e indivisível;&lt;br /&gt;
-&amp;nbsp;átomos&amp;nbsp;iguais são de um mesmo elemento&amp;nbsp;químico;&lt;br /&gt;
- durante as&amp;nbsp;reações, os&amp;nbsp;átomos&amp;nbsp;se separam e se reagrupam, formando&amp;nbsp;novas&amp;nbsp;substâncias.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;ul&gt;&lt;li&gt;Thomson&lt;/li&gt;
&lt;/ul&gt;Analisando as&amp;nbsp;experiências&amp;nbsp;com as descargas&amp;nbsp;elétricas&amp;nbsp;em gases rarefeitos (em pequenas quantidades), nas quais ficou evidenciada a presença&amp;nbsp;de&amp;nbsp;cargas positivas e negativas no interior do&amp;nbsp;átomo, conhecido como modelo pudim de passas.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;ul&gt;&lt;li&gt;Rutherford&lt;/li&gt;
&lt;/ul&gt;A matéria é&amp;nbsp;constituída&amp;nbsp;de átomos que possuem massa e volume.&lt;br /&gt;
- átomo é formado por uma parte central, o núcleo, ao redor do qual giram os&amp;nbsp;elétrons;&lt;br /&gt;
- massa do átomo concentra-se praticamente toda no núcleo.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;ul&gt;&lt;li&gt;Chadwick&lt;/li&gt;
&lt;/ul&gt;- todo núcleo é o conjunto de prótons e elétrons;&lt;br /&gt;
- todos os prótons são&amp;nbsp;idênticos&amp;nbsp;e apresentam uma carga igual a de um elétron, porém de sinal contrário. A massa de prótons é 1836 vezes maior que a dos elétrons.&lt;br /&gt;
