pH to pOH Calculator

Calculate pOH

Formula

The formula to calculate the pOH is:

\[ \text{pOH} = 14 - \text{pH} \]

Where:

What is pOH?

pOH is a measure of the hydroxide ion (OH-) concentration in a solution. It is related to pH, which measures the hydrogen ion (H+) concentration. The pH and pOH values are related by the equation:

\[ \text{pOH} = 14 - \text{pH} \]

This relationship holds true for aqueous solutions at 25°C. Together, pH and pOH can be used to describe the acidity or basicity of a solution.

Example Calculation

Let's assume the following value:

Using the formula to calculate pOH:

\[ \text{pOH} = 14 - 5.5 = 8.5 \]

The pOH value is 8.5.
