Barium Hydroxide Hydrate Extra Pure
SHORT DESCRIPTION
Barium Hydroxide 8-Hydrate Extra Pure is a high-purity, white crystalline compound containing eight molecules of water of crystallization. It is widely used in laboratory chemistry as a strong base in titration, qualitative analysis, and inorganic synthesis. Its high solubility in water and strong alkalinity make it valuable for neutralization reactions, preparation of barium salts, and as a reagent for detecting sulfates, carbonates, and phosphates. In analytical applications, it is often used where precise pH control and minimal contamination are critical. The extra pure grade ensures consistent performance in high-accuracy experiments. It should be handled with care and stored in a tightly sealed container in a cool, dry place, as it is caustic and sensitive to carbon dioxide in the air, which can lead to carbonate formation.
