Calculate the molar concentration of uncomplexed Zn2+ (aq) in a solution that contains 0.22 mol of Zn(NH3)4 2+ per liter and 0.3109 M NH3 at equilibrium. Kf for Zn(NH3)4 2+ is 2.9 X 10^9 I started this way... (0.3109 + 4)2/0.22-x)= 2.9 X 10^9

In which of the following solution would CaC2O4 have the highest molar solubility? Please help. A) 0.01 M NaCl B) 0.01 M H2C2O4 C) 0.01 M Na2C2O4 D) 0.01 M NaHC2O4 E) 0.01 M HCl I think it is E because it is a strong acid and will completely dissociate
