A solution has `10^(-2) M` hydrogen ions in it. The solution is diluted by `100` times. The `pH of the solution is

A

`2`

B

`4`

C

`7`

D

`3`

Text Solution

Verified by Experts

The correct Answer is:
B
`[H^(+)] = 10^(-2)`
It is diluted by `100` times
`:. [H^(+) ] = 10^(-4)`
`P^(H) = -log_(10)[H^(+)] = -log_(10)10^(-4)`
`:. P^(H) = 4`
