Discuss the construction and use of Frost Ebsworth diagrams in the determination of stability of oxidation states.

The arsenic in a 1.22-g sample of a pesticide was converted to As 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 As ? (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?  

Calculate the initial thiocyanate ion concentration, [SCN-]o, in the reaction mixture obtained by combining 2.00 mL of 0.00194 M Fe3+ (aq) with 1250µL of 0.00182 M SCN- (aq). Give your answer in millimolar (mM) to three decimal places. You may assume that volumes of dilute, aqueous solutions are additive.
