Calculate the silver ion concentration in a saturated
solutionof silver (i) sulfate
(ksp = 1.4 x 10-5).

0.015 M

Explanation:

Let's consider the solution of silver (I) sulfate.

Ag₂SO₄(s) ⇄ 2 Ag⁺(aq) + SO₄²⁻(aq)

In order to find the solubility (S) of silver (I) sulfate, we will use an ICE chart.

    Ag₂SO₄(s) ⇄ 2 Ag⁺(aq) + SO₄²⁻(aq)

I                               0               0

C                            +2S           +S

E                               2S            S

The solubility product (Ksp) is:

Ksp = 1.4 × 10⁻⁵ = [Ag⁺]².[SO₄²⁻] = (2S)².S = 4S³

S = 0.015 M
