The pH of a solution ois `3.7`. The concentrations of proton is in the order of

A

`10^(-2)M`

B

`10^(4)M`

C

`10^(-6)M`

D

`10^(-8)M`

Text Solution

Verified by Experts

The correct Answer is:
B
`P^(H)=-"log"_(10)[H^(+)]`
`"log"_(10)]H^(+)]=-P^(H)=-3.7`
`bar (3).7+1-1=4.3`
`[H^(+)]`=antilog 4.3
