The Ksp of the solution is 1.97 * 10^-9.
<h3>What is the pH?</h3>
The pH is defined as the hydrogen ion concentration of the solution. Now we have the pH of the solution as 10.9.
We know that;
pOH = 14 - pH
pOH = 14 - 10.9
pOH = 3.1
[OH^-] = Antilog [-3.1]
[OH^-] =7.9 * 10^-4 M
Now
Ksp = [M^2+] [2OH^-]^2
Ksp = s * (2s)^2
Ksp = 4s^3
Now s = 7.9 * 10^-4 M
Ksp = 4(7.9 * 10^-4)^3
Ksp = 1.97 * 10^-9
