(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.
An interstitial alloy prepared from two metals. metal A with the larger atomic radius has a hexagonal closed-packed structure. What if the formula(for example:A2B,AB,AB2)of the alloy if atoms of metal B occupy the following?
