Study Notes

pH Measurement

pH is a measure of the concentration of hydrogen ions (H+) in a solution.
pH measures the acidity or basicity of a solution.

Acidic Solutions

A pH range of 0-7 indicates acidic solutions.
The lower the pH, the more acidic the solution.

Physiological pH

The physiological pH of body fluids is 7.4, which is slightly alkaline.

Buffer Solutions

The purpose of a buffer solution is to resist changes in pH when an acid or base is added.
Buffer solutions maintain a relatively constant pH despite changes in the solution.
