Sodium acetate and sodium phosphate are common in most buffers from pH 5 - 7, but different chemicals are used for stronger acids, eg acetic acid of hydrochloric acid for stronger acids and sodium carbonate for mildly alkaline or sodium hydroxide for stronger buffers. The link below gives you an idea about some buffers. look under the water research link for a good listing of chemicals used as buffers.

Buffers consist of any weak acid and its conjugate base in similar concentrations. So, you could form a buffer with acetic acid and sodium acetate, sodium bicarbonate and sodium carbonate, ammonium chloride and ammonia, sodium dihydrogen phosphate and sodium hydrogen phosphate....There are thousands of compounds that can be used to produce a buffer system.
