buffer solution

A buffer solution is a special type of liquid that helps maintain a stable pH level, even when acids or bases are added. It typically consists of a weak acid and its corresponding salt (or a weak base and its salt). This combination allows the solution to resist changes in acidity or alkalinity, making it important in various chemical and biological processes, such as in our blood. Buffers are essential in many applications, including laboratories, pharmaceuticals, and environmental science, because they help keep conditions stable and prevent drastic changes that could be harmful.
