The pH of a saturated solution of a metal hydroxide MOH is 10.15. Calculate the Ksp for this compound.

Explanation:

Hello!

In this case, since the pH of the given metal is 10.15, we can compute the pOH as shown below:

Now, we compute the concentration of hydroxyl ions in solution:

Now, since this hydroxide has the form MOH, we infer the concentration of OH- equals the concentration of M^+ at equilibrium, assuming the following ionization reaction:

Whose equilibrium expression is:

Therefore, the Ksp for the saturated solution turns out:
