The concentration of hydrogen ion in a sample of soft drink is `3.8xx10^(-3)M`. What is its `pH`?

Text Solution

Verified by Experts

`pH=-log[3.8xx10^(-3)]`
`=-{log[3.8]+log[10^(-3)]}`
`=-{(0.58)+(-3.0)}=-{-2.42}=2.42`
Therefore the pH of the soft drink is 2.42 and it cann be interred that it is acidic.
