Product Overview
Sodium bicarbonate LR grade is a versatile laboratory reagent known for its high purity and consistent performance in chemical applications. This white, crystalline powder is chemically stable under normal conditions and exhibits excellent solubility in water, making it ideal for precise pH adjustments and buffering solutions. With a molecular formula of NaHCO₃, it maintains a neutral pH of 8.3 in solution, ensuring reliable results in titration and neutralization processes. The LR grade designation guarantees minimal impurities, meeting stringent laboratory standards for analytical work. Its free-flowing nature prevents caking, ensuring accurate measurement and easy handling. The compound decomposes at elevated temperatures, releasing carbon dioxide, which is useful in specific reaction setups. Packaged in moisture-resistant containers, this sodium bicarbonate maintains its integrity during storage and transport, preserving its efficacy for extended periods.
FAQs
1. What is the shelf life of sodium bicarbonate LR grade?
When stored in a cool, dry place in its original sealed container, sodium bicarbonate LR grade maintains its stability for up to 24 months from the date of manufacture.
2. Can this sodium bicarbonate be used for preparing standard solutions?
Yes, the LR grade purity makes it suitable for preparing standard solutions where precise concentration and minimal contaminants are required.
3. How does the LR grade differ from food-grade sodium bicarbonate?
LR grade sodium bicarbonate undergoes stricter purification processes to remove trace metals and other impurities, making it appropriate for laboratory applications rather than food preparation.
4. What precautions should be taken while handling this chemical?
While generally safe, it’s recommended to wear gloves and safety goggles when handling large quantities to avoid skin or eye irritation from dust particles.
5. Is this product compatible with most laboratory glassware?
Yes, sodium bicarbonate LR grade is chemically inert to standard borosilicate glassware and most common laboratory containers under normal conditions.
