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`
