Answer 2

A buffer solution (more precisely, pH buffer or hydrogen ion buffer) 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.
