Qualitative Analysis of Group I Cations

This video describes the concept behind qualitative analysis and goes in details about the different steps in the qualitative analysis of group I cations. In addition, use of centrifuge and positive control is also discussed.

After taking and passing his class and going ahead to the next levels, his videos still help me out to complete other labs!

You explain it better than my professor. Thank you so much.

This really helped me finally understand the cations test. Thank you so much.

[@chanimakavinga510]

Thank you so much. Only now I understand what I did in the lab.

Sir ,this is a good video ,can you make videos about other groups too

Hello! Can I get a copy of the document you showed, Sir?

Hello Doctor .. How can I get the book that contains the subject of the qualitative analysis of cations from the first group? Can you help me please?? 🙏🏻

[@naulichemistry3782]

Hi, not sure about book. But I teach at a college where we make this information available publicly. Here's a direct link (sites.google.com/view/smcchemistry/chemistry/chem-12-experiments?authuser=1)). If you scroll down to Experiment 6, there are documents for the experiment you want. If this answer helps, please let your friends and others know about this channel so I can keep making more videos!

[@nitajusufi7836]

Thank you sir, and please can u make a video for gruop2 please. Respect.

[@naulichemistry3782]

We don't test for Group II here at my college, but if I have time, I'll try to see if I can create one.

[@linsdesk7240]

Good day, sir! why must a large excess of chloride ion be avoided in the precipitation of the group I chlorides?

[@naulichemistry3782]

It may result in difficulty in separating the lead chloride if there's too much chloride ions.

Hello Professor, do you have a book that includes the complete explanation of the elements of the first, second, third and fourth groups? I hope you will answer my question because I need to answer you quickly??And thank you ❤️

[@naulichemistry3782]

Hi, I don’t quite understand the question. There are many things you can describe about these elements, so I need some more specificity with what you’re looking for.

[@mareimz.hasanein3542]

@@naulichemistry3782 I mean Do you own a book from your publications that includes an explanation of mathematical problems related to analytical chemistry ???

[@naulichemistry3782]

@@mareimz.hasanein3542 Hi, I don't have a book on math problems for analytical chem. I make a large number of videos on General Chemistry, many of them require math to solve. You may want to look at those and see if any of them apply to your own situation.

[@mareimz.hasanein3542]

Ok...thank u so much

[@dayelyluisalazosoria797]

I have a question, ¿why we use that specific reagents? Why not others?

[@yuihanashi2659]

Hello Sir! I am quite confused about the most common issue you stated. Do you add HNO3 on the Pb solution?

[@naulichemistry3782]

We don't use nitric acid in this test. At the start we added HCl which precipitates all the cations and also provide the acidic environment needed for the reaction between chromate and Pb2+ ions later.

[@bonbonpony]

Yeah, but… putting all the waste in a container doesn't make it disappear :q What can we do to recycle them into something less nasty? Also I think that such safety precautions should go FIRST in the video, not at the END of it, because if people turn off the video before getting to the end, they might be unaware that they're dealing with some nasty stuff :q

Doctor, why do we use Centrifuge in the experiment?🌺

[@naulichemistry3782]

Centrifuge is used to separate the solid precipitate from the substances that are still in their liquid states. If this answer helps, please let your friends know about this channel so I can keep making videos!

could I get the you are reading plz

[@chattibizahra1600]

Thank you 🥰🥰 plizzz why we use hot water ????

[@naulichemistry3782]

Hot water allows PbCl2 to dissolve, but keep AgCl and Hg2Cl2 to stay precipitated. If this answer helps, please let your friends and others know about this channel so I can keep making more videos!

Hi please need help can get a copy of your presentation

[@amanibk6418]

How can we separate A from B

[@naulichemistry3782]

That's just an example. You'll need something that precipitates A but keeps B soluble or vice versa.

[@anasimad2]

Could you please post the pdf that you explain it in this video , please . I really need it , please

[@naulichemistry3782]

You can copy the information from the YT video. Everything is in the video. I don’t think I have that file anymore.
