2.42 × 10^-3 g of BaSO₄ can dissolve in 1.00 L of water. Calculate K_sp for this salt. A) 1.08 × 10^-10 B) 2.42 × 10^-3 C) 5.86 × 10^-6 D) 1.05 × 10^-5 E) none of these

Question

Quizplus · Accepted Answer

The solubility product (Ksp) for BaSO4 can be calculated using the formula Ksp = [Ba2+][SO42-], where the concentrations of Ba2+ and SO42- ions are equal due to the 1:1 stoichiometry of their dissolution. Given the solubility is 2.42 × 10^-3 mol/L for both ions, Ksp = (2.42 × 10^-3)^2 = 5.86 × 10^-6. However, the correct calculation should consider the stoichiometry and units correctly, leading to the choice provided in the options.
