A colorless crystalline good that is incredibly toxic (0.one g will be a lethal dose). Assessment from the stable and vapor states implies a dimerized construction of As4O6. Inside the processing of As2O3 the oxide is Ordinarily decreased withcarbon: 2As2O3+3C?→As4+3CO2 The response is endothermic and is particularly carried out at http://https//chemscenter.com
