- Chemical formula: CH₃COONa
- Molecular weight: 82.03 g/mol (anhydrous matter); 136.08 g/mol (trihydrate)
- Structure: Composed of the radical acetate ion (CH₃COO⁻) and sodium ion (Na +)
- pH value: The aqueous solution is weakly alkaline, pH is about 8-9
- Appearance:
- Anhydrous sodium acetate: white crystalline powder
- Sodium acetate trihydrate (CH₃COONa*3H₂O): colorless transparent crystal
- Solubility:
- Solvable in water, solubility increases significantly with temperature (at 20°C, about 46.5 g per 100 mL of water)
- Slightly soluble in ethanol, insoluble
- Melting point:
- Anhydrous sodium acetate: 324°C
- Sodium acetate trihydrate: 58°C (dehydration decomposition)
- Density:
- Anhydrous sodium acetate: 1.528 g/cm³
- Sodium acetate trihydrate: 1.45g/cm³
- Hygroscopic: Sodium acetate trihydrate is easy to hygroscopic, and anhydrous sodium acetate hygroscopic is low
Heated decomposition. When heated to high temperatures, sodium acetate decomposes to form sodium carbonate (Na₂CO₃) and methane (CH₄).
