Measuring Acidic and Basic pH

Measuring acidic and basic pH helps describe how a solution behaves. Acids donate protons, or H+ ions, and bases donate hydroxide ions, or OH- ions. When acids and bases are mixed, they can neutralize each other. A neutral substance is neither acidic nor basic.

The pH meter is an electrical device that determines the acidity or basicity of aqueous solutions, one of the most commonly monitored parameters.

To use a pH meter, the pH electrode is first calibrated with standard buffer solutions with known pH values that span the range being measured. To make a pH measurement, the electrode is immersed...
