pH and Buffer Solution Quiz

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.
