`pH` of a `10^(-10) M NaOH` is nearest to

A

`10`

B

`7`

C

`4`

D

`10`

Text Solution

Verified by Experts

The correct Answer is:
B
Total conc. of `[OH^(-)]` in solution
`=[OH-]_((f rom water))+[OH]_(f rom NaOH))`
`=(10^(-7))_((a ppro x))+10^(-10)=slightly more than 10^(-7)`
So `pOH` should be slightly less than `7`
