Sodium Acetate - Sodium Acetate

Japanese: 酢酸ナトリウム - サクサンナトリウム
Sodium Acetate - Sodium Acetate

CH 3 COONa (82.03). The trihydrate is obtained by neutralization of acetic acid with sodium hydroxide, or by double decomposition of calcium acetate with sodium sulfate. The trihydrate is a colorless monoclinic crystal. It is efflorescent, with a melting point of 59 °C. It becomes anhydrous when dried at 120-250 °C. The anhydrous form is a white monoclinic crystal. Density: 1.528 g cm -3 . Melting point: 320 °C. It is hygroscopic, readily soluble in water, and slightly soluble in ethanol. It is used as an analytical reagent, buffer, food preservative, pharmaceutical, photography, plating industry, mordant, dehydrating agent, organic synthesis, etc. [CAS 127-09-3:CH 3 COONa][CAS 6131-90-4:CH 3 COONa・3H 2 O]
