Expert Solution

The equilibrium reaction is as follows:-

The equilibrium constant for the dissociation of copper hydroxide can be written as follows:-

Given that the density of solution of copper hydroxide is 3.37 g/mL

It can be converted to Molarity by dividing the mass by molar mass (97.561 g/mol) and changing volume in mL to L as follows:-

Solubility product expression for this salt is:-

So, equilibrium constant can be calculated as follows:-
