The pOH and the pH are related by the following equation:
[tex]pH+pOH=14[/tex]Thus, we can solve for pH and substitute the pOH = 5 to find the pH:
[tex]\begin{gathered} pH+pOH=14 \\ pH=14-pOH \\ pH=14-5 \\ pH=9 \end{gathered}[/tex]So, the pH is 9.
We can classify the solution by using the folowing:
[tex]\begin{gathered} pH<7\to acid \\ pH=7\to neutral \\ pH>7\to base \end{gathered}[/tex]Since the pH is 9, it is greater than 7, so the solution is a base.
