Thank you :) (By the way, I think you meant 1/a^3[sqrt((u+b)/u)] for the last part, right?)

I have problems with integrating this... :( \int_{0}^{x}\frac{1}{\sqrt{a^2 - b/x}}dx I have tried substituting 1/x with u and so on... But it doesn't seem to work :( Thanks in advance!

Distillation sounds good =p (I'm not sure if it's possible to get 100% purity of *anything* anyway) Do you need the wine for drinking later =p? Column chromatography may be also be an option. You will probably be able to drink the wine afterwards (but not recommended...)

For the first reaction: you should not be expecting any precipitation - tetra-amino cuprate is indeed deep blue in colour but water soluble. The blue precipitate observed was a side reaction of Cu2+ with OH- as the solution become more and more basic on the addition of NH3: Cu2+(aq) + OH-(aq)...
