## 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.

- First, determine the total pH value.
- Next, gather the formula from above = pOH = 14 – pH.
- Finally, calculate the pOH.
- 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** **= ?
