What does pH measure?

pH is a measurement of the acidity or alkalinity of a solution. The pH scale ranges from 0 to 14, where values below 7 indicate acidic conditions, values of 7 are neutral, and values above 7 indicate basic or alkaline conditions. This measurement is crucial in various fields, including chemistry, biology, and environmental science, as it can affect chemical reactions, biological processes, and overall solution behavior.

Understanding pH is vital for operators because it influences processes such as fermentation, water treatment, and chemical manufacturing. Monitoring and controlling pH can help ensure optimal conditions for reactions, product quality, and compliance with safety regulations.
