What are buffer solutions, and how do they maintain a stable pH when small amounts of acid or base are added?
Buffer solutions are mixtures of a weak acid and its conjugate base, or a weak base and its conjugate acid. They work to maintain a stable pH by neutralizing small amounts of added acid or base. When an acid is added to the buffer, the base component neutralizes it, and when a base is added, the acid component does the same. This capacity to resist changes in pH is due to the equilibrium established between the weak acid/base and its conjugate counterparts.
