This chapter is limited to an outline on the chemistry of arsenic compounds which have opportunity environmental importance. A summary of these compounds is supplied in Table 2-one. Inside the processing of As2O3 the oxide is Usually diminished withcarbon: 2As2O3+3C?→As4+3CO2 The response is endothermic which is completed at 500–800℃.The elemental http://https//chemscenter.com
