Question

If the pH of a solution is 12.2, what is the pOH?

Answer 1

pH + pOH = 14

12.2 + pOH = 14

1.8 = pOH

Answer 2

pOH is the concentration of the hydroxide ions in the aqueous solution. The pOH of the solution with pH 12.2 will be 1.8.

What are pH and pOH?

pH is the potential of the hydrogen or the hydronium ion in the solution, while pOH is the potential of the hydroxide ion in the solution. They give the acidity and alkalinity of the solution.

Given, pH = 12.2

pOH is calculated as:

$\begin{aligned} \rm pH + pOH &= 14\\\\\rm 12.2 + pOH &= 14\\\\&= 1.8 \end{aligned}$

Therefore, 1.8 is the pOH of the solution.
