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.
