Product Overview
Barium hydroxide anhydrous (94-98% purity) is a highly reactive alkaline compound widely used in laboratory settings for its strong basic properties and low hygroscopicity. This fine white powder is ideal for applications requiring precise pH control, such as acid-base titrations, where it serves as a reliable standardizing agent. Its anhydrous nature ensures minimal interference from water content, making it particularly suitable for reactions sensitive to moisture. In organic synthesis, it acts as a catalyst or reagent in ester hydrolysis, aldehyde condensations, and other transformations. The compound also finds utility in carbon dioxide absorption due to its ability to form insoluble barium carbonate, which is useful in gas analysis and purification processes. The laboratory reagent grade guarantees consistent performance with minimal impurities, ensuring reproducible results in analytical procedures. Proper handling is essential, as barium hydroxide is corrosive and toxic if ingested or inhaled, requiring standard lab safety protocols during use and storage.
FAQs
1. What is the shelf life of anhydrous barium hydroxide when stored properly?
When stored in a tightly sealed container away from moisture and CO₂, anhydrous barium hydroxide retains its purity for up to 2 years. Exposure to air gradually converts it to the monohydrate form, reducing its effectiveness.
2. Can this compound be used for preparing barium hydroxide solutions?
Yes, it dissolves in water to form a strongly alkaline solution. However, the exothermic reaction requires slow addition to cold water while stirring to prevent excessive heat buildup and potential splattering.
3. What precautions should be taken when handling this chemical?
Wear nitrile gloves, safety goggles, and a lab coat to avoid skin or eye contact. Work in a fume hood due to its corrosive nature, and never ingest or inhale the powder, as barium compounds are toxic.
4. Is this product compatible with glassware for long-term storage?
While glass is chemically resistant to barium hydroxide, prolonged storage may cause etching due to its alkaline nature. Polyethylene or polypropylene containers with airtight seals are recommended for extended storage.
5. How does the anhydrous form differ from the octahydrate version?
The anhydrous form has no bound water molecules, offering higher reactivity and purity for moisture-sensitive applications. The octahydrate contains 8 water molecules per formula unit, making it less suitable for precise analytical work.
