PH8 PH9 Sodium Acetate Acid 58%-60% Purity Fused Sodium Acetate

Industrial Grade 58%~60% Sodium Acetate with pH 8~9 for Chemical Raw Materials

• 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: Soluble 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)
