A buffer is the substance that prevents rapid or large swings in pH. There are two types of buffers; acidic buffers and basic buffers.
A buffer solution is one which resists changes in pH when small quantities of an acid or an alkali are added to it. Acidic buffer solutions An acidic buffer solution is simply one which has a pH less than 7. Acidic buffer solutions are commonly made from a weak acid and one of its salts - often a sodium salt.

A buffer is the substance that prevents rapid or large swings in pH
A buffer is a solution that contains a mixture of a weak acid and it's conjugate base or a weak base and it's conjugate acid. This solution is able to absorb hydrogen (H+) or hydroxide (OH-) and therefore prevent the changes of the pH value of the solution.
