A good buffer contains significant amounts of both a weak acid and its conjugate base. Buffers are used to maintain the pH for a system. the effective buffering range of a buffer is a factor of its pKa, the dissociation constant of the weak acid in the buffering system. Many things, such as changes in temperature or concentrations can affect the pKa of a buffer.
