Product Overview
Potassium bisulfate (KHSO₄) in crystalline form is a highly pure, reagent-grade chemical designed for demanding laboratory applications. This BAKER ANALYZED™ product undergoes rigorous quality control to ensure consistency, making it a reliable choice for precise acid-base reactions and pH adjustments. The crystalline structure provides excellent solubility in water, allowing for rapid dissolution and uniform distribution in solutions. Its stable composition minimizes impurities, reducing the risk of interference in sensitive analytical procedures. The reagent-grade designation guarantees compliance with strict purity standards, ensuring accurate and reproducible results. Potassium bisulfate is particularly valued for its ability to function as a mild acidifying agent without introducing chloride ions, which can be problematic in certain reactions. The 500 g packaging offers a practical quantity for regular lab use while maintaining freshness through secure sealing. This product is an essential component in protocols requiring controlled acidity, where precision and reliability are paramount.
FAQs
1. What is the shelf life of potassium bisulfate crystal reagent?
When stored in a cool, dry place in its original sealed container, potassium bisulfate crystal reagent typically maintains its stability for 2-3 years from the date of manufacture. Always check the label for the exact expiration date.
2. Can this potassium bisulfate be used for food-grade applications?
This product is classified as a reagent-grade chemical and is not certified for food or pharmaceutical use. It is intended solely for laboratory and analytical applications where high purity is required for non-consumable processes.
3. How does potassium bisulfate compare to sulfuric acid for pH adjustment?
Potassium bisulfate offers a more controlled and less corrosive alternative to sulfuric acid for pH adjustment. It dissociates gradually in solution, providing a buffered acidification effect that is easier to manage in sensitive reactions where sudden pH drops could be problematic.
4. What safety precautions should be taken when handling this chemical?
Always wear appropriate personal protective equipment including gloves, goggles, and a lab coat when handling potassium bisulfate. Work in a well-ventilated area or under a fume hood, as the powder can irritate the respiratory tract. Avoid contact with skin and eyes, and wash thoroughly after handling.
5. Is this potassium bisulfate compatible with glass laboratory equipment?
Yes, potassium bisulfate is generally compatible with standard borosilicate glass laboratory equipment. However, prolonged exposure to concentrated solutions may etch glass surfaces over time. For long-term storage of solutions, consider using polyethylene or polypropylene containers.
