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} $ .
