What is [OH^-] in a 0.50 M pyridine (C₅H₅N; K_b = 1.7 * 10^-⁹) solution? A) 1.8 * 10^-⁹ M B) 2.9 *10^-⁵ M C) 0.50 M D) 3.3 *10^-¹⁰ M E) none of these

Question

Quizplus · Accepted Answer

The concentration of OH⁻ can be calculated using the formula for the base dissociation constant (Kb). For pyridine, [OH⁻] = √(Kb × [C5H5N]) = √(1.7 × 10⁻⁹ × 0.50) = 2.9 × 10⁻⁵ M.
