The concentration of hydrogen ion in a sample of soft drink is `3.8 xx 10^(-3)M`. What is its `pH`?

A

`3.84`

B

`2.42`

C

`4.44`

D

`1.42`

Text Solution

Verified by Experts

The correct Answer is:
B
`pH =- log [H^(+)] =- log (3.8 xx 10^(-3)]`
`=- [log (3.8) +log (10^(-3)]`
`=-[(0.58)+(-3.0)]=+2.42`
