Product Overview
Potassium Dichromate LR is a highly stable, orange-red crystalline compound widely recognized for its strong oxidizing properties. With a minimum assay of 99%, this laboratory-grade reagent ensures reliable performance in redox reactions, volumetric analysis, and qualitative inorganic testing. Its low moisture content and high solubility in water make it a preferred choice for preparing standard solutions in titrimetric procedures. The compound’s non-hygroscopic nature ensures long-term stability when stored under recommended conditions. As a potent oxidizer, it is commonly employed in cleaning laboratory glassware by removing organic residues through chromic acid mixtures. The LR grade designation confirms adherence to stringent purity standards, minimizing impurities that could interfere with sensitive analytical processes. This product is packaged in airtight containers to prevent contamination and maintain its efficacy over extended storage periods.
FAQs
1. What is the shelf life of Potassium Dichromate LR when stored properly?
When kept in a tightly sealed container away from moisture and direct sunlight, Potassium Dichromate LR retains its stability for up to 3 years from the date of manufacture.
2. Is this product compatible with plastic containers for storage?
While short-term storage in HDPE or PP containers is possible, prolonged contact may cause degradation. Glass or PTFE-lined containers are recommended for long-term storage.
3. What alternatives exist for applications requiring a less hazardous oxidizing agent?
Potassium permanganate or ceric ammonium nitrate can serve as alternatives in certain redox titrations, though reaction conditions may need adjustment.
4. How should spills of Potassium Dichromate LR be handled in a lab setting?
Spills should be neutralized with a reducing agent like sodium bisulfite, collected with absorbent material, and disposed of as hazardous waste according to local regulations.
5. Does this product meet ISP or BP standards for laboratory reagents?
This LR-grade product conforms to general laboratory reagent specifications but is not certified to pharmacopeial standards like ISP or BP.
