1. Use values of Ksp and Kf for copper (II) hydroxide and its complex to predict if a precipitate should form in a 0.1 M Cu2+ solution that is 3 M in OH-. ((Ksp = 1.3x10^-20 and Kf = 1.3x10^16))?
2. Repeat for 0.1 M Zn^2+ in 3 M OH-
3. What is the appropriate % if complexed iron in a 0.1 M Fe3+ solution containing 1 M KSCN?
