Abstract

The pH of a solution is an important measure of how acidic or alkaline it is. It shows the concentration of hydrogen ions in the solution through a negative logarithm. This measurement gives insight into how a substance behaves chemically. Scientists use a pH electrode to get accurate pH readings, which provides reliable measurements for different tests. pH is a key concept in chemistry and is relevant in many scientific fields, including biochemistry, biology, physics, medicine, agriculture, and environmental science. Keeping the right pH level is crucial in many industries, especially in chemical manufacturing, food production, and environmental protection, as it can directly affect the quality of lab results. Even small changes in pH can lead to major differences in the accuracy of analytical outcomes. This is particularly important when following strict guidelines in pharmacopoeias or conducting research using databases like Scopus and PubMed, where data accuracy is vital. This article explains the essential aspects needed to use pH measurement effectively in analysis. It provides a detailed look at other factors necessary for practical testing. Additionally, it highlights the various ways pH measurements are used, showing their importance across different scientific and industrial areas.
