HClO is a weak acid. The concentration of `H^(+)` ions in 0.1 M solution of HClO `(K_(a) = 5 xx 10^(-8))` will be equal to

A

`7.07 xx 10^(-5)`

B

`5 xx 10^(-9)`

C

`5 xx 10^(-7)` m

D

`7 xx 10^(-4)` m

Verified by Experts

The correct Answer is:

A

`[H^(+)]^(2)= C.alpha = 0.1 xx 5 xx 10^(-8)`
`H^(+) = sqrt(5xx10^(-9)) = 7.07 xx10^(-5) M `
