Question

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. (a) What is the
oxidation state of As in AsO₄^3-? (b) Name Ag₃AsO₄ by analogy
to the corresponding compound containing phosphorus
in place of arsenic. (c) If it took 25.0 mL of 0.102 M Ag⁺
to reach the equivalence point in this titration, what is the
mass percentage of arsenic in the pesticide?
