Question

Calculate the silver ion concentration in a saturated

solutionof silver (I) sulfate
(Ksp = 1.4 x 10-5).

Answer 1

0.015 M

Step-by-step 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
