WebBest. [deleted] • 8 yr. ago. ELI5: A buffer is made up of two types of molecules: an acid and a base. A key feature is that the acid and base are "alternative" forms and the two can switch back and forth. A buffer can resist pH change due to the presence of both molecules. When you add a new acid, it reacts with the base and becomes neutralized. WebJun 29, 2024 · A buffer is simply a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid. Buffers work by reacting with any added acid or base to control the pH.
