Key Concepts

pH Scale

The pH scale is a logarithmic measure of the acidity or basicity of a solution, defined as the negative logarithm of the hydrogen ion concentration. A lower pH indicates a higher concentration of hydrogen ions and greater acidity, while a higher pH indicates a lower concentration of hydrogen ions and greater basicity.

Logarithmic Relationship

Because the pH scale is logarithmic, each unit change in pH represents a tenfold change in hydrogen ion concentration. For example, an increase in pH by 1 means the hydrogen ion concentration decreases by a factor of 10, which is central to understanding how pH relates to the acidity or basicity of a solution.
