3 points Consider the 5 different methods of removing arsenic compounds from drinking water based on real world examples. AsO 3 . Fe3+ ---> Fe(AsO4)(s) 2 AsO4+ 13+3 Fe2+ --->Fez(AsO4)2(s) 3 AsO 43 +5 Ca(OH)2 ---> Cas(AsO4)30H(s) + 9 OH 2 AsO 3 + 3 Ca 2+ ..-> Caz(AsO4)2(s) 2 AsO2 +352 + 4H20 --> As253(s) + 8 OH Note that in all reactions, the arsenic compound from the drinking water is encased inside a solid after the reaction is complete. (Thelons are in the aqueous phase.) 1. If the arsenic compound formed were aqueous, liquid or gas, what would be the outcome of the remediation effective or not? 2. Why is it important in planning a method of arsenic removal from aqueous solutions (water supply) for the arsenic compound after reaction to be a solid? Recall: the density of Ionic solids is greater than the density of water.
