What does the pH index measure?

The pH index is specifically designed to measure the acidity and alkalinity of a solution. It is a numerical scale that indicates the concentration of hydrogen ions in the water, allowing us to understand whether a substance is acidic (pH less than 7), neutral (pH of 7), or alkaline (pH greater than 7). This measurement is crucial in various applications, including water quality assessment, agricultural practices, and food processing, as it can significantly affect chemical reactions, microbial growth, and overall system performance. Understanding the pH helps in managing processes that depend on the balance of acids and bases, making it a vital factor in many fields, including commercial food equipment service.
