Molecule Structure Image



Sodium acetate is the sodium salt of acetic acid. It is used in the textile industry to neutralize sulfuric acid waste streams, and as a photoresist while using aniline dyes. It is also a pickling agent in chrome tanning, and it helps to retard vulcanization of chloroprene in synthetic rubber production. It may be added to foods as a seasoning. As the conjugate base of a weak acid, a solution of sodium acetate and acetic acid can act as a buffer to keep a relatively constant pH. This is useful especially in biochemical applications where reactions are pH dependent. It is also used in consumer heating pads or hand warmers and is also used in hot ice.
