A sparingly soluble salt having general formula A_(x)^(p+) B_(y)^(q-) and molar solubility S is in equilibrium with its saturated solution. Derive a relationship between the solubility and solubility product for such salt.

A sparingly soluble salt having general formula A_(x)^(p+) B_(y)^(q-)

1.	A sparingly soluble salt having general formula A_(x)^(p+) B_(y)^(q-) and molar solubility S is in equilibrium with its saturated solution. Derive a relationship between the solubility and solubility product for such salt.
