Answer» Buffer action: The ability of the buffer solution to resist the changes in pH value on the addition of small amount of an acid or a base is known as buffer action. Buffer solution: A buffer solution is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical applications. |
