Enoble Eding 2. A mixture weighing 27.73 mg containing only FeCl2 (FW 126.75) and KCI (FVW 74.55) required 18.49 mL of 0.02237 M AgNO; for complete titration of the chloride. Find the weight percent of FeCl2 in the mixture. A soil sample weighing 0.8729 g was digested in nitric acid and diluted to 100.00 mL with water. A 25.00 mL aliquot of this solution was titrated with 0.02718 M Ce requiring 18.34 mL for complete oxidation of Fe 2+ to Fe3+. 3. Calculate the weight % of Fe in the original sample For Extra Practice (not to hand in): Chapter 6, pp 140- 142: 4, 5, 6, 8, 9, 12 s O
