Phosphate Buffer Solution

A phosphate buffer solution is a liquid mixture that helps maintain a stable pH level, or acidity, in a system by balancing the amounts of phosphate ions. It contains two types of phosphate compounds that can either release or absorb hydrogen ions (H+), which are responsible for acidity. This ability to adjust and resist changes in pH makes phosphate buffer solutions essential in biological and chemical experiments, ensuring environments remain consistent. They are commonly used in laboratories, medical tests, and biological research to keep conditions optimal without sudden shifts in acidity or alkalinity.
