Ionic equilibrium

Question

A weak monobasic acid is 0.01% ionised, its concentration is 1 M. Hence, [OH^-] is

Moderate

A

$1 \times 10^{- 4} M$
B

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

$1 \times 10^{4} M$
D

$1 \times 10^{10} M$

Solution

$[H^{+}] = C α = 1 \times \frac{0 .01}{100} = 1 \times 10^{- 4} M ∴ [{OH}^{-}] = \frac{K_{w}}{[H^{+}]} = \frac{1 \times 10^{- 14}}{1 \times 10^{- 4}} = 1 \times 10^{- 10} M$
