SATHEE: Equilibrium Question 306

Equilibrium Question 306

Question: The dissociation of water at $25^{o} C$ is $1.9 \times 10^{- 7}$ and the density of water is $1.0, g / c m^{3} .$ The ionisation constant of water is [IIT 1995]

Options:

A) $3.42 \times 10^{- 6}$

B) $3.42 \times 10^{- 8}$

C) $1.00 \times 10^{- 14}$

D) $2.00 \times 10^{- 16}$

Show Answer

Answer:

Correct Answer: D

Solution:

$α = 1.9 \times 10^{- 9}$ ; $C = \frac{1000}{18}$

$K = \frac{[H^{+}] [O H^{-}]}{(H_{2} O)} = C α^{2}$

$= 1.9 \times 10^{- 9} \times 1.9 \times 10^{- 9} \times \frac{1000}{18}$

$= 2.0 \times 10^{- 16}$ .
