Copper sulphate investigation


To whom it may concern I am an A-level student studying chemistry in the UK and I would like your help so please could you send me some information on investigating the concentration of copper sulphate via titration using Iodine and sodium thiosulphate.

If possible could you send me results and a method of how you would do the experiment,if you could I would be very grateful.

yours faithfully

Get hold of any analytical chemistry book (it's also in a good number of plain chemistry books). That analysis is extremely old and has not changed a bit. A good book like "The Chemical Analysis of Electroplating Solutions" [linked by editor to info about book at Amazon] has to be available on an interlibrary loan and will literally lead you by the hand thru the how and why that it works.

Hi, I am also a student and I have just come across your question and was wondering if you got any feedback? if so, I would be extremely grateful if you could pass it on to me as I have been looking everywhere and can't find a thing.
yours thankfully,

Hi, Rachel.

C'mon, Cousin; the feedback that Kevin received was "Get hold of any analytical chemistry book . . . and will literally lead you by the hand". Have you really been looking everywhere -- including the library -- and still been unable to find any analytical chemistry book? The first one listed on Amazon, "Analytical Chemistry: An Introduction" [link is to product info at Amazon], looks to contain a titration for copper with iodine. Good luck with it!
