(a) Derive the Cu2+ hydroxide solubility diagram given in class. Show your derivations for the lines and then plot the lines and include the solubility or CT,Cu as a function of pH (a log C - pH diagram). (b) Now, what if ammonia is present? Redraw the Cu solubility diagram with ammonia complexes present for a CT,NH3 = 0.01 M.
