Explanation:

Solubility product constant is usually written as (Ksp). It is defined for equilibrium between a solids and its respective ions in a solution. Its value indicates the degree to which a compound dissociates into ions in water. The higher the solubility product constant, the more soluble the compound.

Solubility of a solute is defined as the maximum amount of solute that can be dissolved in a solvent at equilibrium while the solubility product constant (Ksp) describes the equilibrium between a solid and its constituent ions in a solution.

For AB2(s)< > A(aq) + 2B(aq). But solubility of AB2= x

Ksp= x × (2x)^2

Ksp= 4x^3
