The Ksp of Cd(OH)2 is 5.3 x 10^-15 at 298 K. (a) Calculate the molar solubility of Cd(OH)2 at 298 K in a solution buffered at a pH of 8.77.(b) At 298 K, 100 mL of 0.100 M Cd(NO3)2 is mixed with 100 mL of 0.300 M KOH. Assume that the volumes are additive. Using this information, answer the following sub-questions: (i) Calculate the molarity of OH- in the resulting solution after the reaction goes to completion. (ii) Calculate the molarity of Cd2+ in the resulting solution once equilibrium is established.
