Chinese name: crystalline sodium acetate Chinese alias: sodium acetate trihydrate, crystalline sodium acetate, sodium acetate crystal, sodium acetate trihydrate English alias: sodium acetate trihydrate, sodium acetate chemical formula C2H3NaO2 3H2O is colorless, transparent, crystalline or white particles with a relative molecular weight of 136.08. Weathering in dry air, losing crystal water at 120℃. At higher temperature, 0. 1g is dissolved in 0.8ml water, 0.6ml boiling water and 19ml ethanol. At 25℃, the pH value of 0. 1mol/L aqueous solution is 8.9, the relative density is 1.45 and the melting point is 58℃. Sealed determination of lead, copper and nickel.

That is, the product of sodium acetate losing three crystal waters.
