(a) The Ksp of Cu(OH)2 is 4.8 x 10-20, calculate the concentration of Cu+2 at equilibrium. Cu(OH)2(s, excess)Cu+2(aq) + 2OH-(aq) (b) The Ksp of Zn(OH)2 is 3.0 x 10-16, calculate the equilibrium concentration of OH-. Zn(OH)2(s, excess)Zn+2(aq) + 2OH-(aq) c) (Common Ion Problem)Excess Ag2CO3 is added to an 0.2 M K2CO3solution. Calculate the equilibrium concentration of Ag+ under these conditions.Ksp for Ag2CO3 is 8.1 x 10-12. Ag2CO3(s, excess)2Ag+(aq) + CO3-2(aq)
