| Testing Indicators | Appearance — Visual inspection; Identification — Reaction with ferric salts producing characteristic acetate complex; Assay — Acid-base titration or non-aqueous titration method; Sodium content — Flame photometry or ICP-OES; Water content — Karl Fischer titration or loss on drying method; pH — Determination of aqueous solution pH (GB/T 9724); Insoluble matter — Gravimetric filtration method; Chloride — Ion chromatography or argentometric titration; Sulfate — Turbidimetric method; Heavy metals — ICP-MS or atomic absorption spectroscopy. |
| Storage Notes | Store in a cool, dry, and well-ventilated place. Keep the container tightly sealed and protected from moisture because sodium acetate trihydrate can lose crystal water when exposed to dry air or elevated temperatures. Avoid contact with strong acids and strong oxidizing agents. Store away from excessive heat. |
| Lead Time | 10 days |
Sodium acetate trihydrate is widely used as a buffering agent, pH regulator, and chemical reagent. It is commonly applied in pharmaceutical formulations, biochemical laboratories, food additives, textile processing, electroplating, photographic chemicals, and industrial buffer systems. It is also used for preparing acetate buffer solutions and as a source of acetate ions in chemical synthesis.
