Sagot :
Answer:
pH = 9.81
pOH = 4.19
Explanations:
The formula for calculating the pOH of a solution is given as:
[tex]pOH=-log[OH^-][/tex]Given the following parameters
[tex][OH^-]=6.5\times10^{-5}M[/tex]Substitute
[tex]\begin{gathered} pOH=-log(6.5\times10^{-5}) \\ pOH=-(-4.19) \\ pOH=4.19 \end{gathered}[/tex]Determine the pH of the solution
[tex]\begin{gathered} pH+pOH=14 \\ pH=14-pOH \\ pH=14-4.19 \\ pH=9.81 \end{gathered}[/tex]Therefore the pH and pOH are 9.81 and 4.19 respectively
