Easy definition of buffer solution |
| Answer» Buffers are solutions that resist change in pH on dilution or on the addition of small amounts of acids or alkali.\xa0A lot of biological and chemical reactions need a constant pH for the reaction to proceed. Buffers are extremely useful in these systems to maintain the pH at a constant value. This does not mean that the pH of buffers does not change. It only means that the change in pH is not as much as it would be with a solution that is not a buffer. | |
