Using pK_a(CH3COOH) = 4.76 and pK_a(H2O) = 15.7, the value of log_10K for CH3COOH + OH- CH3COO- + H2O is closest to

JEE Main levelSingle correct optionDifficulty 2 of 3g2117

Using $p K_{a} (CH X_{3} COOH) = 4.76$ and $p K_{a} (H X_{2} O) = 15.7$ , the value of $lo g_{10} K$ for $CH X_{3} COOH + OH X^{-} CH X_{3} COO X^{-} + H X_{2} O$ is closest to

lo g K = p K_{a} (conjugate acid of base) - p K_{a} (acid) = 15.7 - 4.76 = 10.94 \approx 10.9

. A large positive value means the reaction is essentially complete.
