Description

Magnesium Hrdroxide Molecular formula: Mg(OH)2 Molecular weight: *8.3 CAS No: ********8 EINECS No: ********3 Appearance: white powder Specification: White crystalline or powder; and its aqueous solution show alkaline reaction; 2.*6g/cm3. It is soluble in diluted acid and ammonium salt solution and almost insoluble in water and alcohol. Its solubility *8in water is 0.***9g/**0g. It is easy to absorb carbon dioxide in the air. When it is heated to above **0 in alkaline solution, it will become hexagonal crystal system crystalline. At **0, it shall decompose into magnesium oxide and water, and change into magnesium oxide by losing water above **0.
