Answer: 12.4
Explanation: pH or pOH is the measure of acidity or alkalinity of a solution.
Acids have pH ranging from 1 to 6.9 and bases have pH ranging from 7.1 to 14.Neutral substances have pH of 7.
First we have to calculate the pH.
[tex]pH=-\log [H^+][/tex]
[tex]pH=-\log (0.025)[/tex]
[tex]pH=1.60[/tex]
Now we have to calculate the pOH.
[tex]pH+pOH=14\\\\pOH=14-pH\\\\pH=14-1.60=12.4[/tex]
Thus pOH of the solution is 12.4
