pH determination is a test for acidity/basicity.
pH determination is important because it provides information about the acidity or alkalinity of a solution. It is crucial in various fields such as chemistry, biology, and environmental science to understand how pH affects chemical reactions, biological processes, and environmental conditions. Monitoring pH levels can help in maintaining optimal conditions for processes and organisms.
An accurate measurement is made with a pH-meter; pH-papers make only approximative determination.

The electrometric method of pH determination provides a single value dependent on the concentration of hydrogen ions in the aqueous solution being tested. The colorimetric method of pH determination uses acid-base indicators to provide a range of values for a solution's pH, and is therefore less accurate than the electrometric method.
The acidity or alkalinity of a substance can be determined using a pH indicator. pH indicators change color depending on the pH of a solution, allowing for the determination of whether the substance is acidic, neutral, or basic.
The determination of an liquids's pH is by the ratio of the volume of the liquid to the amount of hydrogen ions concentrated in the liquid
The indicator used in potentiometric titrations is typically a pH electrode. By measuring changes in pH during the titration process, the endpoint of the titration can be determined accurately. The pH electrode provides a continuous measurement of the solution's pH, allowing for a precise determination of the equivalence point.
pH stands for "potential of hydrogen." It is a measure of the acidity or alkalinity of a solution, ranging from 0 (most acidic) to 14 (most alkaline). pH indicators are substances that change color based on the pH of a solution, allowing for easy visual determination of its acidity or alkalinity.
