Product Overview
Barium hydroxide octahydrate (99.95% trace metal basis) is a high-purity alkaline compound widely used in laboratory settings for its strong basic properties and excellent solubility in water. This crystalline solid appears as colorless monoclinic crystals that rapidly absorb carbon dioxide from the air, making it essential to store under inert conditions. The product’s 99.95% purity ensures minimal metallic impurities, making it ideal for sensitive applications requiring precise chemical reactions. Its octahydrate form provides stable hydration, while the trace metal basis grade guarantees consistency in analytical procedures. The compound’s high alkalinity (pH ~13 in solution) enables efficient neutralization reactions and serves as a reliable reagent for preparing barium salts. With a molecular weight of 315.46 g/mol and a density of 2.18 g/cm³, this barium hydroxide variant offers predictable stoichiometry in quantitative analyses. The product is particularly valued for its ability to form insoluble barium salts, which is critical in gravimetric analysis and precipitation techniques.
FAQs
1. What is the shelf life of barium hydroxide octahydrate when stored properly?
When stored in a tightly sealed container away from moisture and carbon dioxide, the product maintains its specified purity for up to 24 months from the date of manufacture.
2. Can this grade be used for preparing standard solutions in titration?
The 99.95% trace metal basis grade is suitable for preparing standard solutions, though you may need to perform standardization against a primary standard for critical titration work.
3. What precautions should be taken when handling this chemical?
Always wear appropriate PPE including gloves, goggles, and lab coat. Work in a well-ventilated area or fume hood as the compound is corrosive and toxic if ingested or inhaled.
4. Is this product compatible with glass containers for long-term storage?
Yes, but ensure the glass container has an airtight seal and consider adding a desiccant packet to absorb any residual moisture that could cause caking.
5. How does the octahydrate form differ from the anhydrous version in applications?
The octahydrate form offers better solubility in water and is generally preferred for solution-based applications, while anhydrous forms are used when water content must be strictly controlled.
