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
