The molar solubility of magnesium carbonate is 1.8 Ã— 10â€“4 mol/l. What is ksp for this compound?

Serhud [2]

Answer:

3.2 × 10⁻⁸

Explanation:

Let's consider the solution of magnesium carbonate.

MgCO₃ ⇄ Mg²⁺(aq) + CO₃²⁻(aq)

We can relate the molar solubility (S) with the solubility product (Ksp) using an ICE chart.

MgCO₃ ⇄ Mg²⁺(aq) + CO₃²⁻(aq)

I 0 0

C +S +S

E S S

The Ksp is:

Ksp = [Mg²⁺] × [CO₃²⁻] = S × S = S² = (1.8 × 10⁻⁴)² = 3.2 × 10⁻⁸
