This article delves into the significance of pH management, its applications across various fields, common methods of pH adjustment, and best practices for monitoring and maintaining optimal pH levels.

## The Science of pH ### What is pH?

pH, a term coined in 1909 by Danish chemist Søren P. L. Sørensen, stands for "potential of Hydrogen." It quantifies the concentration of hydrogen ions (H ) in a solution. The mathematical definition of pH is given by the formula: pH = -log[H ]. Hence, the higher the concentration of hydrogen ions, the more acidic the solution, and vice versa for basic (alkaline) solutions. The pH scale is a logarithmic scale, which means that each whole number change on the scale represents a tenfold change in acidity or alkalinity.

Understanding pH involves recognizing the role of hydrogen ions in chemical reactions. When acids are dissolved in water, they release H , leading to a decrease in pH. Conversely, bases release hydroxide ions (OH-), which can neutralize excess H , resulting in an increase in pH. This fundamental knowledge of acids and bases is essential for manipulating pH, especially in contexts like agriculture, water treatment, and chemical manufacturing.
