Enter the total pH value into the pOH Calculator. The calculator will evaluate the pOH. This calculator can also determine the pH given the pOH.

## pOH Formula

The following two example problems outline the steps and information needed to calculate the pOH.

pOH = 14 - pH
pH = 14 - pOH
• pOH is the pOH
• pH is the total pH value

To calculate pOH, simply subtract the pH value from 14.

## How to Calculate pOH?

The following steps outline how to calculate the pOH.

1. First, determine the total pH value.
2. Next, gather the formula from above = pOH = 14 – pH.
3. Finally, calculate the pOH.
4. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

the total pH value = 8

pOH = 14 – pH = ?
