A buffer resists changes in pH by absorbing or releasing protons. It consists of a weak acid and its conjugate base or a weak base and its conjugate acid. When an acid is added, the buffer neutralizes it by accepting protons. When a base is added, the buffer donates protons to neutralize it.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
