Answer;

pH = 7

pOH = 7

Explanations:

The formula for calculating the pOH of a solution is given as:

[tex]pOH=-log[OH^-][/tex]

Given the following parameter

[tex][OH^-]=1.0\times10^{-7}M[/tex]

Substitute

[tex]\begin{gathered} pOH=-log(1.0\times10^{-7}) \\ pOH=-log(10^{-7}) \\ pOH=-(-7) \\ pOH=7 \end{gathered}[/tex]

Determine the pH of the solution

Recall that pH + pOH = 14, hence;

[tex]\begin{gathered} pH=14-pOH \\ pH=14-7 \\ pH=7 \end{gathered}[/tex]

Hence the required pH and pOH of aqueous solution are 7 and 7 respectively
