Product Overview
Oxalic acid dihydrate (ARS, ACS grade) is a high-purity crystalline compound widely used in laboratory settings for its precise chemical properties. This reagent-grade oxalic acid meets stringent American Chemical Society (ACS) specifications, ensuring a minimum assay of 99.5%, making it suitable for critical applications where accuracy is paramount. The dihydrate form provides stability and ease of handling, while its strong reducing properties allow for effective use in redox titrations and metal cleaning processes. The compound’s low hygroscopicity ensures consistent performance even in humid conditions, a common challenge in Indian lab environments. Its water-soluble nature enables quick dissolution for solution preparation, while the absence of heavy metal impurities (≤5 ppm) prevents interference in sensitive analytical procedures. The product is packaged in airtight containers to maintain purity during storage and transportation, with each batch accompanied by a certificate of analysis for quality verification. The crystalline structure remains stable under normal lab conditions, though it should be stored away from direct sunlight and incompatible substances like strong oxidizers. This particular grade of oxalic acid dihydrate is especially valued for its role in standardizing potassium permanganate solutions, where its precise molecular weight (126.07 g/mol) enables accurate molar concentration calculations. The compound’s effectiveness in removing rust and scale from glassware makes it a staple in lab maintenance protocols across educational and research institutions.
FAQs
1. What is the difference between ARS and ACS grade oxalic acid?
ARS (Analytical Reagent Standard) and ACS (American Chemical Society) grades both indicate high purity, but ACS grade follows stricter specifications set by the American Chemical Society. This product meets both standards, ensuring maximum purity for critical applications.
2. Can this oxalic acid be used for preparing standard solutions?
Yes, this ARS/ACS grade oxalic acid dihydrate is specifically suitable for preparing standard solutions due to its high purity (99.5%+) and precise molecular weight, which allows for accurate molar concentration calculations.
3. How should I store oxalic acid dihydrate to maintain its purity?
Store in a tightly sealed container in a cool, dry place away from direct sunlight and incompatible substances like strong oxidizers. Keep the container properly labeled and out of reach of moisture to prevent degradation.
4. Is this oxalic acid suitable for cleaning laboratory glassware?
Yes, the high purity and strong reducing properties make it effective for removing rust, scale, and metal stains from laboratory glassware without leaving residues that could interfere with subsequent experiments.
5. What safety precautions should be taken when handling this chemical?
Always wear appropriate personal protective equipment including gloves, goggles, and lab coat. Handle in a well-ventilated area or fume hood, as oxalic acid can be harmful if inhaled or absorbed through skin. Avoid contact with eyes and skin, and wash thoroughly after handling.
