Question

What is the pH of a solution with a hydrogen ion concentration of `3.5*10^-4`?

Answer 1

`pH` `=` `-log_(10)[H_3O^+]`

Explanation:

`pH` `=` `-log_(10)(3.5xx10^-4)` `=` `-(-3.46)`

`=` `3.46`

Using antilogarithms. can you tell me the `pH` of a solution that is `10^-7` `mol*L^-1` with respect to `H_3O^+`.
