Molecular formula : MW : CAS :
nature : As2O3 also known as Asian arsenic anhydride. Impure commonly known as arsenic or arsenic trioxide (white arsenic). There are three variants. Colorless monoclinic crystal density of 4.15 in 193 ° Csublimation. Colorless cubic crystal relative density of 3.865 (25 / 4 ° C), 193 ° C sublimation. With no fixed physical density of 3.738, melting point 315. Water-soluble generation 0.2968. The first two crystals dissolve in alcohol, acid and alkali. With no fixed physical alkali - soluble and insoluble in alcohol. Highly toxic! The precipitation with ferric hydroxide-burned by the mixture of magnesium can be used as antidotes. For the glass industry, and the preparation of drugs, pesticides, herbicides, etc.. Or sublimation calcined ore containing arsenic derived.
