Solution
The correct option is B Solubility product
The equilibrium constant for a chemical reaction in which a solid ionic compound dissolves to yield its ions in solution is called solubility product.
we calculate by CuSO4(s)⇌Cu2++SO42−
Solubility product for above equilibrium is Ksp=[Cu2+][SO42−]
where [Cu2+] and [SO42−] are concentrations of ions which are dissociated from CuSO4.
