Structure | ![]() |
chemical properties | Soluble in alkali, slightly soluble in water, solubility at 0 DEG C to 1.2% DEG C, 100 to 11.5%, the water solution containing arsenic trioxide HAsO2. In dilute hydrochloric acid (1.5 ~ 2.5 rub / L), the solubility is very small, and the solubility of concentrated hydrochloric acid is increased, and the three is produced. Dissolve in alcohol. This product is a compound amphoteric acid, acid is higher than that of alkaline soluble arsenite in alkali generation. There are two kinds of crystal type: 1. The claudetite monoclinic crystal. When the temperature is high, the glass is formed, and the temperature is 193. The single crystals and cubic crystals were dissolved in ethanol, acids and bases, and the shape was soluble in acids and bases, but not in ethanol. boiling point:465°C,flash point:465°C,density:3.738g/cm3,Water solubility:37g/L(20°C) |
