Question

What is the concentration of silver(I) ions in a saturated solution of silver(I) sulfate?

Ksp(Ag2SO4) = (1.277x10^-5)

Answer 1

Ag₂SO₄(s) <==> 2Ag⁺(aq) + SO₄^2-(aq)

Ksp = [Ag⁺]²[SO₄]^2-

Let x = [SO₄]^2-, then [Ag⁺] = 2x

1.277x10^-5 = (2x)²(x) = 4x³

x³ =3.19x10^-6

x = [SO4]^2- = 1.47x10^-2 M

[Ag⁺] = 2x = 2 * 1.47x10^-2 M = 2.94x10^-2 M
