Question

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

Answer 1

The pH of the solution is 7.16.

Step-by-step 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:

`\begin{gathered} pH=-log\lbrack H_3O^+\rbrack \\ pH=-log(6.9x10^(-8)) \\ pH=7.16 \end{gathered}`

So, the pH of the solution is 7.16.
