The formula to calculate the pOH is:
\[ \text{pOH} = 14 - \text{pH} \]
Where:
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.
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.
