High Purity 58%~60% Sodium Acetate Trihydrate White Crystal for Buffer Agent
- 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: colorless transparent crystal
- Solubility: Soluble in water (46.5 g per 100 mL at 20°C), 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 hygroscopic, while anhydrous sodium acetate has low hygroscopicity
When heated to high temperatures, sodium acetate decomposes to form sodium carbonate (Na₂CO₃) and methane (CH₄).
