Key Concepts

Buffer Solution

A buffer solution is a system composed of a weak acid and its conjugate base (or a weak base and its conjugate acid) that resists changes in pH when small amounts of acid or base are added. This resistance to pH change makes buffers crucial in maintaining stable environments in chemical and biological systems.

Henderson-Hasselbalch Equation

The Henderson-Hasselbalch equation is an essential formula that links the pH, the acid’s pKa, and the ratio of the concentrations of the conjugate base to the acid. It enables the calculation of the required proportions of acid and conjugate base to achieve a desired pH in a buffer solution.

Conjugate Acid-Base Pair

A conjugate acid-base pair consists of a weak acid and its corresponding base formed by the loss of a proton, or a weak base and its conjugate acid formed by the gain of a proton. The balance between these pairs determines the buffering capacity and the pH of the solution as described by the Henderson-Hasselbalch equation.
