What is the acid ionization constant , K _a, for lactic acid, CH₃CH(OH)COOH, if the base ionization constant, K _b, of CH₃CH(OH)COO^- equals 7.1×10^{- 11}?

Question

Quizplus · Accepted Answer

The relationship between the acid ionization constant (Ka) and the base ionization constant (Kb) for a conjugate acid-base pair is given by the equation Ka * Kb = Kw, where Kw is the ionization constant of water at 25°C, equal to 1.0 × 10^-14. Given Kb = 7.1 × 10^-11 for the conjugate base of lactic acid, solving for Ka gives Ka = Kw / Kb = (1.0 × 10^-14) / (7.1 × 10^-11) = 1.4 × 10^-4.
