Answer:

Ksp = 0.01145

Explanation:

  • SrSO4 ↔ Sr2+  +  SO42-
  •  S               S            S...........................in the equilibrium

∴ S = 0.107 g/L = [ Sr2+ ] = [ SO42- ]

  • Ksp = [ Sr2+ ] * [ SO42- ]

⇒  Ksp = S * S = S²

⇒ Ksp = ( 0.107 )²

⇒ Ksp = 0.01145

Answer:

Ksp = 3.4 × 10⁻⁷

Explanation:

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

[tex]S=\frac{0.107g}{(183.68g/mol).1.0L} =5.8 \times 10^{-4} M[/tex]

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
