Our Sodium Oxalate (CAS 62 - 76 - 0) is a high - quality product offered at the best price. Sodium oxalate has the chemical formula Na₂C₂O₄. It appears as a white, odorless powder. The molar mass of sodium oxalate is approximately 134.00 g/mol. It is highly soluble in water, with a solubility of about 3.7 g/100 mL at 20°C. The density of sodium oxalate is around 2.34 g/cm³. It has a melting point of about 250 - 270°C, where it decomposes. This product is synthesized through a carefully controlled chemical process to ensure its high purity and quality.
Sodium oxalate has a wide range of applications in various industries. In the chemical analysis field, it is commonly used as a primary standard for standardizing potassium permanganate solutions. This is crucial in redox titrations where accurate measurement and quantification of substances are required. In the textile industry, sodium oxalate is used as a bleaching agent. It helps in removing impurities and stains from fabrics, giving them a clean and bright appearance. In the photography industry, it serves as a reducing agent. It can help in the development process of photographic films and papers, contributing to high - quality image production. Moreover, in the metal finishing industry, sodium oxalate is used for metal surface treatment. It can form a protective layer on the metal surface, preventing corrosion and improving the durability of the metal.
When using sodium oxalate for chemical analysis, first, accurately weigh an appropriate amount of sodium oxalate according to the experimental requirements. Dissolve it in a suitable amount of distilled water in a clean volumetric flask. Then, carefully transfer the solution to a titration flask. When using it as a bleaching agent in the textile industry, prepare a solution of sodium oxalate with a proper concentration in a large container. Immerse the fabrics into the solution and ensure they are fully soaked. Stir gently for a certain period according to the fabric type and the degree of staining. For its use in photography, prepare a developer solution with sodium oxalate as one of the key components. Follow the specific recipe and mix the chemicals precisely to achieve the desired development effect. In metal finishing, create a treatment bath with the appropriate sodium oxalate concentration. Immerse the metal parts into the bath for a specific time to form the protective layer.
**Case 1: Chemical Analysis in a Laboratory**
A chemistry laboratory needs to standardize a potassium permanganate solution. The technician weighs 0.2 g of our high - quality sodium oxalate accurately. After dissolving it in 50 mL of distilled water, sulfuric acid is added to acidify the solution. Then, the potassium permanganate solution is slowly titrated into the sodium oxalate solution until the solution turns a faint pink color. By using our pure sodium oxalate, the technician can accurately determine the concentration of the potassium permanganate solution, with a high level of precision in the titration results.
**Case 2: Textile Bleaching in a Factory**
A textile factory has a batch of cotton fabrics with stubborn stains. They prepare a 5% sodium oxalate solution in a large bleaching tank. The cotton fabrics are immersed in the solution for 30 minutes with gentle agitation. After rinsing, the fabrics show a significant improvement in whiteness and stain removal. The use of our high - quality sodium oxalate ensures that the bleaching process is efficient and does not damage the fabric fibers.
**Case 3: Photography Development in a Studio**
A professional photography studio is developing black - and - white films. They use a developer solution containing sodium oxalate as a reducing agent. By following a specific recipe, they mix the chemicals precisely. The developed films have clear images with well - defined tones, thanks to the proper function of sodium oxalate in the development process.
**Case 4: Metal Finishing in a Manufacturing Plant**
A metal manufacturing plant wants to improve the corrosion resistance of its steel parts. They create a treatment bath with a 3% sodium oxalate solution. The steel parts are immersed in the bath for 20 minutes. After the treatment, the steel parts show enhanced corrosion resistance, which extends their service life in harsh environments.
