when naturally occuring arsenic becomes solubilized and contaminates water sources it can result in arsenic poisoning. arsenic with the oxidation state in H3AsO3 is more toxic than in H3AsO4. the balanced one electron reduction half reaction for reduction of H3AsO4 to H3AsO3 is 1/2H3AsO4 (aq) + H+ (aq) + e- ~> 1/2H3AsO3 (aq) + 1/2H2O (l) -what is oxidation state of As in H3AsO3 -what is oxidation state of As in H3AsO4 -given the standard Ecell for the reduction half reaction is +0.56 V, write an equation for pE in terms of pH and the ratio of two arsenic containing species -the pH of a particular sample is 2.00 and the pE value is 8.97 what is the ratio of H3AsO3(aq) to H3AsO4(aq) in this system

Electrolysis

Electrolysis is defined as the process of breaking down ionic compounds into their constituent elements by passing a direct electric current through the compound in a fluid state. The cathode reduces cations, while the anode oxidizes anions. An electrolyte, electrodes, and some form of external power source are the main components required for conducting electrolysis. A partition, such as an ion-exchange membrane or a salt bridge, may also be used, but this is optional. These are primarily used to prevent the products from diffusing near the opposing electrode.
