Answer: pOH of the solution is 13.41.
Explanation:-
pH is the measure of acidity or alkalinity. It is also defined as negative logarithm of hydrogen ion concentration.
\(pH=-log[H^+]\)
\(pOH=-log[OH^-]\)
\(pH+pOH=14\)
Given: \([H^+]\) = 0.253
Thus \(pH=-log[0.253]\)
\(pH=0.59\)
\(0.59+pOH=14\)
\(pOH=14-0.59=13.41\)
