Question

Accepted Answer

A pH meter is a device used to measure the acidity or alkalinity of a solution.

A pH meter consists of a probe that measures the voltage difference between a reference electrode and a glass electrode.
The pH value is determined by comparing the voltage difference to a known standard.
pH meters are commonly used in laboratories, agriculture, and water treatment to monitor and control pH levels.
For example, in a laboratory, a pH meter can be used to measure the pH of a chemical solution to ensure it is within the desired range for a specific experiment.
