The arsenic in a 1.22 g sample of a pesticide was converted to AsO4 3- by suitable chemical treatment. It was then titrated using Ag+ to form Ag3AsO4 as a precipitate. What is the oxidation state of As in AsO4 3-? Name Ag3AsO4 by ogy to the corresponding compound containing phosphorus in place of arsenic. If it took 25.0 mL of 0.102 M Ag+ to reach the equivalence point in this titration, what is the m percentage of arsenic in the pesticide?
