Calculate the maximum concentration (in M)of magnesium ions (Mg⁺²)in a solution that contains 0.025 M of CO₃^2-. The K_sp of MgCO₃ is 3.5 × 10^-8. A)1.8 × 10^-5 B)1.4 × 10^-6 C)2.8 × 10^-6 D)3.2 × 10^-10 E)8.1 × 10^-12

Question

Quizplus · Accepted Answer

The solubility product expression for MgCO₃ is Ksp = [Mg²⁺][CO₃²⁻]. Given Ksp = 3.5 × 10⁻⁸ and [CO₃²⁻] = 0.025 M, solve for [Mg²⁺]: [Mg²⁺] = Ksp / [CO₃²⁻] = (3.5 × 10⁻⁸) / 0.025 = 1.4 × 10⁻⁶ M.
