AIPMT PRELIMS 2010 Chemistry Solubility Product MCQ Question
Type: MCQ-numerical-Medium-Class 11
If pH of a saturated solution of Ba(OH)₂ is 12, the value of its Kₛₚ is
A
5.00 × 10⁻⁷ M³
B
00 × 10⁻⁶ M³
C
00 × 10⁻⁷ M³
D
5.00 × 10⁻⁶ M³
Correct Answer
Option A
Detailed Explanation
pH = 12, so pOH = 2, [OH⁻] = 10⁻². Ba(OH)₂ ⇌ Ba²⁺ + 2OH⁻, S = 5 × 10⁻³ M, Kₛₚ = [Ba²⁺][OH⁻]² = 5 × 10⁻⁷ M³.
