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

Dec 8, 2016

$p H = 8$

#### 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:

$p H = - \log \left(1 \times {10}^{- 8} M\right) = 8.$

Therefore, the pH of the solution is 8.
