The solubility of strontium carbonate is 0.0011 g/100 mL at 20ºC.Calculate the K_sp value for this compound.

Question

Quizplus · Accepted Answer

The solubility product constant (Ksp) can be calculated using the solubility of the compound. For SrCO3, the dissolution is SrCO3(s) ⇌ Sr²⁺(aq) + CO₃²⁻(aq). The molar mass of SrCO3 is approximately 147.63 g/mol. The solubility in mol/L is 0.0011 g/100 mL × (1 mol/147.63 g) × (1000 mL/1 L) = 7.45 × 10⁻⁶ mol/L. Ksp = [Sr²⁺][CO₃²⁻] = (7.45 × 10⁻⁶)² = 5.6 × 10⁻⁹.
