Description
A chemical or combination of chemicals that minimizes the change in pH of a solution when an acid or alkali is added. Buffers are usually a weak acid (or base) paired with its conjugate salt. Many natural substances, such as sea water, soil and blood contain buffers. Examples of buffer pairs are:
- Acetic acid / Sodium acetate: buffers at 4.6
- Monobasic potassium phosphate / dibasic sodium phosphate: buffers at 6.8
- Ammonium chloride / Ammonium hydroxide: buffers at 9.2
- Sodium bicarbonate / Sodium carbonate: buffers at 10.0
Synonyms and Related Terms
Puffer (Deut.); tampon (Fr.); pH buffer; buffers
