C2H3NaO2 Sodium Acetate Ph8.0-Ph9.0 For Environmental Protection Field

• Chemical formula: CH₃COONa
• Molecular weight: 82.03 g/mol (anhydrous); 136.08 g/mol (trihydrate)
• Structure: Composed of acetate ion (CH₃COO⁻) and sodium ion (Na+)
• pH value: Weakly alkaline aqueous solution (pH 8-9)

• Appearance: White crystalline powder (anhydrous) or colorless transparent crystals (trihydrate)
• Solubility: Highly soluble in water (46.5g/100mL at 20°C), slightly soluble in ethanol
• Melting point: 324°C (anhydrous), 58°C (trihydrate decomposition)
• Density: 1.528 g/cm³ (anhydrous), 1.45 g/cm³ (trihydrate)
• Hygroscopic: Trihydrate is highly hygroscopic

When heated to high temperatures, sodium acetate decomposes to form sodium carbonate (Na₂CO₃) and methane (CH₄).

Removes residual chlorine in water through chemical conversion to harmless chloride. Used in drinking water treatment and industrial water systems to prevent equipment corrosion.

Environmentally friendly alternative for road and airport deicing, with lower corrosion impact than traditional salts.

Promotes microbial degradation of organic pollutants by providing a carbon source. Effective for oil and pesticide contaminated soils.

• Waste gas treatment: Absorbs acidic gases (SO₂, HCl) in industrial emissions
• Green chemistry: Replaces toxic chemicals in environmentally sensitive processes
