Sodium Oxalate

Sodium Oxalate is an inorganic compound composed of sodium ions (Na+) and oxalate ions (C2O4^2−). It is commonly used in various industrial and laboratory applications.

Chemical Formula: Na2C2O4

Appearance: A white, crystalline powder or colorless crystals.

Uses:

• Analytical Chemistry: Sodium oxalate is used as a standard reagent in analytical chemistry for the determination of calcium ions (Ca^2+) in various samples. It forms insoluble calcium oxalate precipitates in the presence of calcium ions, which can be quantitatively analyzed.

• Laboratory Reagent: It is used as a laboratory reagent for various chemical reactions and experiments, including precipitation reactions, titrations, and complexometric analyses.

• Metal Cleaning and Polishing: Sodium oxalate may be used in metal cleaning and polishing applications, particularly for removing rust, tarnish, and stains from metal surfaces. It can help dissolve metal oxides and restore the appearance of metal objects.

• Photography: It finds application in the photographic industry as a reducing agent and fixing agent in certain photographic processes.

• Chemical Manufacturing: It serves as a precursor and intermediate in the production of various organic and inorganic chemicals, including oxalic acid, potassium oxalate, and other oxalate salts.
