The solubility of srso4 in water is 0.107g in 1.0 l at 25 degrees celcius. what is the value for ksp for srso4?

Ksp = 3.4 × 10⁻⁷

Explanation:

First, we will express the solubility in molarity (molar mass = 183.68 g/mol).

Let's consider the solution of SrSO₄.

SrSO₄(s) ⇄ Sr⁺²(aq) + SO₄²⁻(aq)

To relate the solubility (S) to the solubility product (Ksp) we will use an ICE chart. We recognize 3 stages (Initial, Change, Equilibrium) and complete each row with the concentration or change in the concentration.

     SrSO₄(s) ⇄ Sr⁺²(aq) + SO₄²⁻(aq)

I                          0               0

C                        +S            +S

E                          S              S

Ksp = [Sr⁺²].[SO₄²⁻] = S² = (5. 8 × 10⁻⁴)² = 3.4 × 10⁻⁷
