The solubility of barium carbonate is 14.8 mg L^-1 at 30 °C. Calculate the K_sp value for BaCO_3.

Question

Quizplus · Accepted Answer

The solubility product (Ksp) is calculated using the formula Ksp = [Ba²⁺][CO₃²⁻]. Given the solubility of BaCO₃ is 14.8 mg/L, convert this to moles/L (mol/L) using the molar mass of BaCO₃ (197.34 g/mol). This gives a concentration of 7.5 × 10⁻⁵ mol/L for both Ba²⁺ and CO₃²⁻ ions. Therefore, Ksp = (7.5 × 10⁻⁵)² = 5.6 × 10⁻⁹.
