دی سدیم اگزالات

Disodium oxalate is a white, crystalline inorganic salt that serves as a source of oxalate ions and sodium ions in aqueous solutions. It is commonly used in laboratories for analytical chemistry and as a reagent in synthesis processes.

🏭⚗️ Production
Disodium oxalate is produced by neutralizing oxalic acid with sodium hydroxide or sodium carbonate under controlled conditions, followed by crystallization and drying to obtain the pure salt.

🔬 Properties
The chemical formula is Na₂C₂O₄ with a molar mass of approximately 134.00 g/mol. It appears as a white, odorless crystalline powder that is soluble in water but insoluble in alcohol. It decomposes on heating to produce sodium carbonate, carbon monoxide, and carbon dioxide.

🧪 Applications
In laboratories, disodium oxalate is used as a primary standard for standardizing potassium permanganate solutions in redox titrations. It is also employed in coordination chemistry and as a chelating agent. In pharmaceutical research, it can be used in studies involving oxalate metabolism and crystallization.

⚠️ Safety
Disodium oxalate should be handled with care as oxalate compounds can be toxic if ingested or inhaled. It may cause irritation to skin, eyes, and respiratory tract. Proper personal protective equipment such as gloves, goggles, and masks is recommended during handling. It should be stored in a dry, well-ventilated area away from acids and incompatible substances.
