BUFFER SOLUTIONS A buffer solution is a solution of (1) a weak acid or a weak base and (2) its salt; both components must be present. The solution has the ability to resist changes in pH upon the addition of small amounts of either an acid or a base. Buffers are important to chemical and biological systems. A buffer must contain a relatively large concentration of acid to react with any OH - ions that may be added to the solution, and must contain a similar concentration of base to react with any added H + ions. The acid and the base components of the buffer must not consume each other in a neutralization reaction. These requirements are satisfied by a weak acid-base conjugate pair. The buffering capacity , that is, the effectiveness of the buffer solution , depends upon the amounts of acid and conjugate base from which the buffer is made. The larger the amount, the greater the buffering capacity.
