application of buffer capacity
What is a buffer capacity?
The buffer capacity is the amount of acid or base that can be added to a given volume of a buffer solution before the pH changes significantly, usually by one unit. Buffer capacity depends on the amounts of the weak acid and its conjugate base that are in a buffer mixture. The more concentrated the buffer solution, the greater its buffer capacity.
What is a buffer solution?
A buffer solution is a solution where the pH does not change significantly on dilution or if an acid or base is added at constant temperature. Its pH changes very little when a small amount of strong acid or base is added to it.
Why does a buffer have a higher capacity for added acid?
And when the concentration of conjugate base is greater than the concentration of weak acid, the buffer has a higher capacity for added acid than added base. As an example, let's think about blood, which has a pH of 7.4.
Do buffer solutions keep pH constant?
Buffer solutions do not have an unlimited capacity to keep the pH relatively constant (Figure 7.2.1 7.2. 1 ). If we add so much base to a buffer that the weak acid is exhausted, no more buffering action toward the base is possible.
