How does an acidimeter work?

An acidimeter measures the acidity of a solution, typically using a pH meter or indicator. The pH meter consists of a glass electrode sensitive to hydrogen ion concentration and a reference electrode, which together provide a voltage that correlates to pH levels. As the electrode is immersed in the solution, it generates a reading that indicates the solution's acidity or alkalinity. The results are usually displayed on a digital screen, allowing for quick and accurate assessment of acidity levels.
