Question

The [`H^+`] (`H^+` concentration) in a solution is `1 x 10^-8` M. What is the pH of the solution?

Answer 1

`pH = 8`

Explanation:

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

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

`pH = -log (1xx10^(-8)M) = 8.`

Therefore, the pH of the solution is 8.
