Equilibrium Question 269

Question: Dissociation constant of a weak acid is $ 1\times {10^{-4}} $ . Equilibrium constant of its reaction with strong base is [UPSEAT 2003]

Options:

A) $ 1\times {10^{-4}} $

B) $ 1\times 10^{10} $

C) $ 1\times {10^{-10}} $

D) $ 1\times 10^{14} $

Show Answer

Answer:

Correct Answer: B

Solution:

$ K_{H}=\frac{K_{a}}{K_{w}}=\frac{{10^{-4}}}{{10^{-14}}}=\frac{1}{{10^{-10}}}=10^{10} $ .
