pH of a centimolar solution of a mono basic acid is `6`. The dissociation constant is approximately equal to

A

`10^(-12)`

B

`10^(-8)`

C

`10^(-10)`

D

`10^(-6)`

Text Solution

Verified by Experts

The correct Answer is:
C
`P^(H) = 6 , C=0.01`
`[H^(+)] = 10^(-6)`
`[H^(+)] = sqrt(K_(a) xx C)`
`K_(a) = 10^(-10)`
