Consider the reaction CaSO 4 (s) Ca 2 + (aq) + SO 4 2- (aq) At

Question:

Consider the reaction

CaSO₄(s) ⇌ Ca²⁺(aq) + SO₄^2-(aq)

At 25°C, the equilibrium constant is K_c = 2.4 × 10^-5 for this reaction.

(a) If excess CaSO₄(s) is mixed with water at 25°C to produce a saturated solution of CaSO₄, what are the equilibrium concentrations of Ca²⁺ and SO₄^2-?

(b) If the resulting solution has a volume of 1.4 L, what is the minimum mass of CaSO₄(s) needed to achieve equilibrium?
