Question

What is the `[H^+]` in a solution that has a pH of 3.35?

Answer 1

`[H^+]=4.47xx10^(-4)M`

Explanation:

The pH of a solution is usually found by the following expression:

`pH=-log[H^+]`

Therefore, to find the concentration of `H^+` we can rearrange this expression and thus,

`[H^+]=10^(-pH)`

`=>[H^+]=10^(-3.35)=4.47xx10^(-4)M`
