The `pH` of `10^(-8)M` solution of `HCl` in water is

A

`8`

B

`-8`

C

Between `7` and `8`

D

Between `6` and `7`

Text Solution

Verified by Experts

The correct Answer is:
D
`10^(-8) M HCI`
At such a low concentration the contribution of `[H^(o+)]` from water cannot be neglected, which is `10^(-7)`. In such cases, the `pH` of the acid can be calculated to be slightly less than `7`.
