pH buffer

A pH buffer is a solution that helps maintain a consistent acidity or alkalinity level in a liquid. It does this by neutralizing added acids or bases, preventing large changes in pH. Buffers Typically contain a weak acid and its conjugate base (or vice versa), which work together to stabilize pH. This is important in biological systems and chemical processes where maintaining a specific pH is essential for proper function and stability. Essentially, buffers act like a pH thermostat, keeping the environment steady despite external changes.
