A colorless crystalline sound that is quite poisonous (0.1 g could be a lethal dose). Examination in the reliable and vapor states suggests a dimerized framework of As4O6. In the processing of As2O3 the oxide is Typically diminished withcarbon: 2As2O3+3C?→As4+3CO2 The response is endothermic which is performed at five hundred–800℃.The elem
