Question: the generic metal hydroxide moh2 has ksp 1451018 note...
The generic metal hydroxide M(OH)2 has Ksp = 1.45×10−18. (NOTE: In this particular problem, because of the magnitude of the Ksp and the stoichiometry of the compound, the contribution of OH− from water can be ignored. However, this may not always be the case.)
A) What is the solubility of M(OH)2 in pure water?
B) What is the solubility of M(OH)2 in a 0.202 M solution of M(NO3)2?
