Answer: C) 12.40

Step-by-step explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration and pOH is calculated by taking negative logarithm of hydroxide ion concentration.


pH=-\log [H^+]


pOH=-log{OH^-}


pH+pOH=14

Given:
[H^+]=0.025 M


pH=-log[0.025]


pH=1.6


1.6+pOH=14


pOH=12.40

Thus pOH of the solution is 12.40
