SATHEE: Equilibrium Question 353

Equilibrium Question 353

Question: The degree of dissociation of $0.1, M, H C N$ solution is 0.01%. Its ionisation constant would be [RPMT 1999]

Options:

A) $10^{- 3}$

B) $10^{- 5}$

C) $10^{- 7}$

D) $10^{- 9}$

Show Answer

Answer:

Correct Answer: D

Solution:

$H A$ ⇌ $H^{+} + A^{-}$

$K = C a^{2} = 0.1 \times {(10^{- 4})}^{2} = 10^{- 9}$
