Buffer solutions are useful in many chemical reactions as they allow the addition of a small amount of acid/ base without changing the pH.
They normally consist of either a weak acid and its salt or a weak base and its salt.
Ammonium acetate buffer is a mixture of ammonium acetate and acetic acid.

Adding H+ or OH- will shift the (top) ethanoic acid equilibrium to the left or right respectively (le chatelier's principle)
When acid is added to the buffer it reacts with the weak base present (CH COO )
When base is added to the buffer it reacts with the weak acid present (CH COOH)
