This chapter is limited to an outline in the chemistry of arsenic compounds which have likely environmental significance. An index of these compounds is provided in Desk 2-one. During the processing of As2O3 the oxide is Ordinarily lessened withcarbon: 2As2O3+3C?→As4+3CO2 The response is endothermic which is completed at 500–800℃.The elemental http://https//chemscenter.com
