The molar solubility of magnesium carbonate is 1.8 * 10^-4 mol/L. What is K_sp for this compound

Question

Quizplus · Accepted Answer

The solubility product constant (Ksp) for magnesium carbonate (MgCO3) is calculated using the formula Ksp = [Mg²⁺][CO₃²⁻]. Since the molar solubility is 1.8 * 10⁻⁴ mol/L, both [Mg²⁺] and [CO₃²⁻] are 1.8 * 10⁻⁴ mol/L. Therefore, Ksp = (1.8 * 10⁻⁴)² = 3.24 * 10⁻⁸, which is approximately 3.2 * 10⁻⁸.
