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

A

`4.32`

B

`5.12`

C

`3.31`

D

`2.42`

Text Solution

Verified by Experts

The correct Answer is:
D
`pH = - log [3.8 xx 10^(-3)] = 2.42`
Therefore, the pH of the solf drink is 2.42 and its is acidic.
