medium

$HClO$ is a weak acid. The concentration of ${H^ + }$ ions in $0.1\,M$ solution of $HClO\,({K_a} = 5 \times {10^{ - 8}})$ will be equal to

A

$7.07 \times {10^{ - 5}}\,m$

B

$5 \times 10^{-9}\,\,m$

C

$5 \times {10^{ - 7}}\,m$

D

$7 \times {10^{ - 4}}\,m$

Solution

(a) ${[{H^ + }]^2} = C\,.\,\alpha = 0.1 \times 5 \times {10^{ – 8}}$

${H^ + } = \sqrt {5 \times {{10}^{ – 9}}} = 7.07 \times {10^{ – 5}}$ $M.$
