Answer:

Step-by-step explanation:
Solubility product is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as
The equation for the ionization of the is given as:

Molar concentration =

By stoichiometry of the reaction:
1 mole of
gives 1 mole of
and 1 mole of

When the solubility of
is S moles/liter, then the solubility of
will be S moles\liter and solubility of
will be S moles/liter.
