Any chemistry the pH of a solution as a measure of the acidity or alkalinity of a solution

Answer:
The pH of the solution is 7.16.
Explanation:
To calculate the pH of a solution we have to replace the hydronium ion concentration (6.9X10^-8 moles/liter) in the pH formula:
[tex]\begin{gathered} pH=-log\lbrack H_3O^+\rbrack \\ pH=-log(6.9x10^{-8}) \\ pH=7.16 \end{gathered}[/tex]So, the pH of the solution is 7.16.
