The Ksp of calcium sulfate, CaSO4, is 9.0 × 10-6. What is the concentration of CaSO4 in a saturated solution? A. 3.0 × 10-3 Molar B. 9.0 × 10-3 Molar C. 3.0 × 10-6 Molar D. 9.0 × 10-6 Molar

The concentration of  in a saturated solution is

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  is given as:

of  =

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.

Thus concentration of  in a saturated solution is
