Incompatible with strong oxidizing agents, halogens. Moisture sensitive. Sodium acetate, CH 3 COONa, also abbreviated NaOAc, [1] also sodium ethanoate, is the sodium salt of acetic acid. This colourless salt has a wide range of uses. Synonyms: Acetic acid sodium salt;Sodium acetate;Anhydrous sodium acetate;Natriumacetat;Octan sodny;Acetic acid sodium salt anhydrous;Niacet sodium acetate anhyd. tech;Sodium acetate anhydrous Appearance White granular powder Structure Crystal structure monoclinic Industrial Sodium acetate is used in the textile industry to neutralize sulfuric acid waste streams, and as a photoresist while using aniline dyes. Sodium Acetate is used as a pickling agent in chrome tanning. In rubber manufacturing it helps retard vulcanization of chloroprene in synthetic rubber. In processing cotton for disposable cotton pads, sodium acetate is used to eliminate the buildup of static electricity. Concrete longevity Sodium acetate is used to reduce the damage water can potentially do to concrete by acting as a concrete sealant, while also being environmentally benign and cheaper than the epoxy alternative that is usually employed for sealing concrete against water permeation. Buffer solution As the conjugate base of acetic acid, a solution of sodium acetate and acetic acid act as a buffer to keep a relatively constant pH. This is especially useful in biochemical applications where reactions are pH dependent in a mildly acidic range (pH 4-6). Heating pad Sodium acetate is also used in many consumer heating pads, hand warmers, and "hot ice. " Sodium acetate trihydrate crystals melt at 58.4°C, [4] (to 58°C [5] ) dissolving in their water of crystallization. When they are heated to around 100°C, and subsequently allowed to cool, the aqueous solution becomes supersaturated. This solution is capable of cooling to room temperature without forming crystals. By clicking on a metal disc in the heating pad, a nucleation centre is formed which causes the solution to crystallize into solid sodium acetate trihydrate again. The bond-forming process of crystallization is exothermic. [6][7][8] The latent heat of fusion is about 264–289 kJ/kg. [5] Unlike some other types of heat packs that depend on irreversible chemical reactions, sodium acetate heat packs can be easily recharged by placing in boiling water for a few minutes until all crystals are dissolved; they can be reused many times.
