Calculate the molar solubility of aluminum phosphate in water given that K_sp = 1.3 *10^-²⁰.

Question

Quizplus · Accepted Answer

The dissolution of aluminum phosphate (AlPO4) in water can be represented as: AlPO4(s) ⇌ Al³⁺(aq) + PO₄³⁻(aq). The Ksp expression is Ksp = [Al³⁺][PO₄³⁻]. Let the molar solubility be 's', then Ksp = s². Solving for 's' using Ksp = 1.3 × 10⁻²⁰ gives s = √(1.3 × 10⁻²⁰) ≈ 1.1 × 10⁻¹⁰ M.
