This chapter is restricted to a description from the chemistry of arsenic compounds which have opportunity environmental relevance. A listing of these compounds is presented in Table 2-one. Inside the processing of As2O3 the oxide is normally decreased withcarbon: 2As2O3+3C?→As4+3CO2 The response is endothermic and is particularly performed at 500–800℃.The http://https//chemscenter.com
