SATHEE: Equilibrium Question 311

Equilibrium Question 311

Question: Hydrogen ion concentration of an aqueous solution is $1 \times 10^{- 4} M$ . The solution is diluted with equal volume of water. Hydroxyl ion concentration of the resultant solution in terms of mol $d m^{- 3}$ is [KCET 2001]

Options:

A) $1 \times 10^{- 8}$

B) $1 \times 10^{- 6}$

C) $2 \times 10^{- 10}$

D) $0.5 \times 10^{- 10}$

Show Answer

Answer:

Correct Answer: C

Solution:

$[H^{+}] = 1 \times 10^{- 4} M \Rightarrow [H^{+}] [O H^{-}] = 1 \times 10^{- 14}$ \ $[O H^{-}] = \frac{1 \times 10^{- 14}}{0.5 \times 10^{- 4}} = 2 \times 10^{- 10}$ M
