Answer:
8.4
Explanation:
pOH refers to a measure of hydroxide ion (OH-) concentration. It denotes the alkalinity of a solution. Aqueous solutions at 25 degrees Celsius with
If pOH is less than 7 then an aqueous solution is alkaline, if pOH is greater than 7 then an aqueous solution is acidic and if pOH is equal to 7 then an aqueous solution neutral.
[tex]pOH=-\log \left [ OH^{-} \right ][/tex]
[tex]pOH=-\log \left [ 3.76\times 10^{-9} \right ]=8.4[/tex]
