Description
Description
Barium hydroxide is a white solid, soluble in water, and has a density of 3.675 g/mL. It is highly corrosive and should be used with care. It should be placed in a tight container and kept in a sealed container in a cool, dry place.
Chemical properties
It will not be decomposed if it is used and stored in accordance with the specifications.
Can corrode glass. Similar to other alkali metal hydroxides, barium hydroxide is a strong base and is deliquescent. Commonly used in the laboratory is barium hydroxide monohydrate. Avoid contact with acidic materials.
Physical properties
It is hygroscopic and soluble in water. The saturated aqueous solution contains 70.63% of Cs2O at 30 °C, and is soluble in ethanol. Azide, chromate, iodide and the like can be processed from hydroxide.

C:CorrosiveSpecial fire fighting procedure
1. Barium hydroxide is not a flammable product. The fire extinguishing agent used shall be fire extinguishing for the surrounding substances.
2. The melting point temperature of this substance is high. If it is hot or molten, it will cause a violent reaction and will ignite combustible materials.
3. This substance also reacts with various metals (eg lead, zinc, etc.) to produce hydrogen.
4. Be careful not to splash the material when it is extinguished. As the substance dissolves in the water, it will release a lot of heat.
5. Remove the container from the fire in the case of a security permit.
6. Firefighters should make personal protection first.
