We’re being asked to determine the solubility of M(OH)2 in a solution buffered at pH = 7.0, 10.0, and 14.0.

Since the M(OH)2 is an ionic compound, it forms ions when dissociating in water.

The dissociation of M(OH)2 in water is as follows:

The hydroxide ion, OH, has a charge of –1. M then has a charge of +2:

M(OH)2(s)  M2+(aq) + 2 OH(aq)

Since the solution is buffered, we can calculate an initial OH concentration from the given pH.
