Buffers do so by being composed of certain pairs of solutes: either a weak acid plus a salt derived from that weak acid, or a weak base plus a salt of that weak base. For example, a buffer can be composed of dissolved acetic acid (HC 2 H 3 O 2, a weak acid) and ...

For the weak base ammonia (NH 3), the value of K b is 1.8x10-5, implying that the K a for the dissociation of its conjugate acid, NH 4 +, is K w /K b =10-14 /1.8x10-5 = 5.6x10-10. Thus, the pK a for NH 4 + = 9.25, so buffers using NH 4 + /NH 3 will work best ...
