Buffer Definition: A buffer is a solution containing either a weak acid and its salt or a weak base and its salt, which is resistant to changes in pH.
Acid-base buffers confer resistance to a change in the pH of a solution when hydrogen ions (protons) or hydroxide ions are added or removed. An acid-base buffer typically consists of a weak acid, and its conjugate base (salt) (see Equations 2-4 in the blue box, below).any people today are interested in exercise as a way of improving their health and physical abilities.
