Product Overview
Potassium carbonate, anhydrous LR is a high-purity, white crystalline powder widely used in laboratory settings for its strong alkaline properties and stability. This laboratory reagent (LR) grade ensures minimal impurities, making it suitable for analytical applications where precision is critical. The anhydrous form eliminates moisture interference, providing consistent results in titrations, buffer preparations, and chemical synthesis. Its free-flowing nature ensures easy handling and accurate weighing, while its solubility in water allows for quick dissolution in aqueous solutions. The compound’s high thermal stability makes it ideal for reactions requiring controlled pH adjustments or as a drying agent in organic synthesis. Compatible with most glassware and standard lab equipment, this Potassium Carbonate variant maintains its efficacy across a broad temperature range. Store in a tightly sealed container to prevent moisture absorption and contamination, ensuring long-term reliability for your experiments.
FAQs
1. What is the difference between anhydrous and hydrated Potassium Carbonate?
Anhydrous Potassium Carbonate contains no water molecules, offering higher purity and stability for moisture-sensitive applications. Hydrated forms include bound water, which may affect reactions requiring precise stoichiometry.
2. Can this LR-grade Potassium Carbonate be used for food applications?
No, this LR-grade variant is specifically formulated for laboratory use and is not certified for food or pharmaceutical applications. For edible purposes, food-grade Potassium Carbonate must be used.
3. What is the shelf life of this product when stored properly?
When stored in a cool, dry place in an airtight container, anhydrous Potassium Carbonate LR retains its stability for up to 3–5 years. Avoid exposure to humidity to prevent caking.
4. Is this compatible with plastic labware?
While generally stable, prolonged contact with certain plastics may cause degradation. Use glass or chemically resistant containers like HDPE for long-term storage or reactions.
5. How does LR grade differ from AR grade in Potassium Carbonate?
LR (Laboratory Reagent) grade is suitable for general lab use with moderate impurity limits, while AR (Analytical Reagent) grade undergoes stricter purification for high-precision analytical work. Choose based on your tolerance for trace contaminants.
