Answer :

Answer:

The pH of the solution is 10.7.

Explanation:

To calculate the pH of the solution it is necessary to replace the concentration of H3O+ in the pH formula:

[tex]\begin{gathered} pH=-log\lbrack H_3O^+\rbrack \\ pH=-log(1.8*10^{-11}) \\ pH=10.7 \end{gathered}[/tex]

So, the pH of the solution is 10.7.
