Barium Hydroxide
H.S.CODE: 28164000
CAS NO.: 12230-71-6
Molecular formula: Ba(OH)2
Property: Colorless transparent crystal or white powder. Easily soluble in water and carbinol, slightly soluble in ethanol, hardly dissolve in acetone. Has strong corrosiveness. Rapidly absorb carbon dioxide from air to be barium carbonate, then does not dissolve in water completely. Relative density: 2.188. Melting point: 78℃. Poisonous.
Use: Applied for determining the carbon dioxide in the air and the chlorophyll, precipitated and separate SO4 to compose barium salt. Served for refining the sugar as well as animal and vegetable oil, intenerating the boiler water.
Packing: In 25kgs plastic woven bag or according to the buyer request.
