용도약한 산과 강한 염기가 만드는 염이므로 수용액은 약한 알칼리성을 보인다. 완충용액의 조제, 염료의 매염제(媒染劑) 로 사용되며, 융해열이 크기 때문에 난방기구의 보온재로도 사용된다.
용도Sodium acetate trihydrate is used in various applications. It is used as a buffer of a pH range in between to 4.0 to 6.0. It is also used in the purification and precipitation of nucleic acids and in protein crystallization. It is used as a mordant dyeing, as a pickling agent in chrome tanning, as a neutralizer in waste streams containing sulfuric acid, in the textile industry and as a photoresist while using aniline dyes. It plays an important role to retard vulcanization of chloroprene in synthetic rubber production. It is a precursor to prepare ester from alkyl halide. Other applications are in photography, as an additive to food, in purification of glucose, in preservation of meat, in tanning, and as a dehydrating agent. In analytical chemistry it is used to prepare buffer solution.
일반 설명Sodium acetate trihydrate can be obtained from the crystallization of sodium acetate in water. On heating at 75°C, it melts, while on heating above 120°C it loses water of crystallization and gets converted into anhydrous form. The hyperfine proton and 13C splittings have been evaluated by recording ESR spectra of its irradiated single crystals. ESR studies suggested the existence of trapped methyl radicals. Its crystals are monoclinic and its crystal structure has been investigated by photographic methods. Unit cell parameters were evaluated.

Sodium acetate is prepared by reacting sodium hydroxide or sodium carbonate with acetic acid in aqueous solution. The solution is evaporated to obtain hydrated crystals of sodium acetate. NaOH + CH3COOH → CH3COONa + H2O Na2CO3 + CH3COOH → 2CH3COONa + CO2 + H2O
