Question

What is the pH of a `8.4x10^-6 M` `H^+` solution?

Answer 1

`pH` = 5.08

Explanation:

The pH can be obtained directly from the concentration using the formula below:

Take the -logarithm of the concentration of hydronium ions that are in the solution:

`pH = -log (8.4xx10^(-6)M) = 5.08`

`color(blue)("Note")`: `H_3O^(+)` is the same as `H^(+)`. This is because we're assuming that water molecules interact with `H^(+)` in solution.
