Answer:
A covalent bond is a result of sharing electrons between two atoms. The main difference between electrovalent and covalent bond is that electrovalent bond is formed when two atoms are in an electrostatic attraction whereas covalent bond is formed when two atoms share their electrons with each other.

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
