Solving pOH Values

Worksheet Description

This worksheet offers a comprehensive approach to understanding and solving problems related to pOH and pH. By completing it, students can solidify their grasp on the basicity and acidity of solutions.

The primary goals of this worksheet are to:

Understand the concept of pOH and how it relates to pH.

Develop skills in calculating pOH, pH, and associated ion concentrations.

Concepts

pOH – This term refers to the negative logarithm (base 10) of the concentration of hydroxide ions ([OH-]) in a solution. The pOH provides a measure of a solution’s basicity. A lower pOH indicates a higher concentration of hydroxide ions and, therefore, a more basic solution.

pH – This is the negative logarithm (base 10) of the concentration of hydrogen ions ([H+]) in a solution. It measures a solution’s acidity.

Relationship between pH and pOH – The sum of pH and pOH for any aqueous solution at 25°C is always 14.
