Answer 2

Given: The solubility of calcium hydroxide in water is s.

To find: We have to find the solubility product of calcium hydroxide.

Solution:

Calcium hydroxide dissociates in water as follows-

$Ca(OH)_2\rightarrow Ca^{+2}+2OH^-$.

Calcium hydroxide dissociates to give calcium and hydroxide ions.

The solubility product of calcium hydroxide is given as-

$Ksp= [Ca^{+2}][OH^-]^2$

The solubility of calcium hydroxide in water is s.

So, its solubility product will be-

$Ksp= s×{2s}^2$

$Ksp= 4s^3$

The solubility product of calcium hydroxide is $4s^3$
