Hi everyone,
Basically, I need to conduct an experiment to work out the concentration of copper ions in a solution of copper sulphate solution (CuSO4.5H2O). One of the methods I'm using has to be gravimetric analysis, but it's not on the syllabus (so no textbook help), and I can't find any useful links online of how to carry out a procedure.
I need get a copper precipitate by displacing the copper ions with zinc ones (from zinc powder).
Can anyone explain it to me? I have so many questions! How do I know how much zinc to add? It just seems like I should be adding zinc until I just 'know' it's enough...
Any help...muchos appreciated!
