1. Solve the following queries (parts a), b), & c)) dealing with volumetric analysis. Make sure you show complete procedures a) A solid mixture weighing 0.05485 g contained only ferrous ammonium sulfate and ferrous chloride. The sample was dissolved in 1 M H₂SO4, and the Fe²+ required 13.39 mL of 0.012 34 M Ce4+ for complete oxidation to Fe³+ (Ce4+ + Fe²+ → Ce³+ + Fe³+). Calculate the weight percent of Cl in the original sample. FeSO4 (NH4)2SO4.6H₂O Ferrous ammonium sulfate FM 392.13 FeCl₂ 6H₂O Ferrous chloride FM 234.84

1. Solve the following queries (parts a), b), & c)) dealing with volumetric analysis. Make sure you show complete procedures a) A solid mixture weighing 0.05485 g contained only ferrous ammonium sulfate and ferrous chloride. The sample was dissolved in 1 M H₂SO4, and the Fe²+ required 13.39 mL of 0.012 34 M Ce4+ for complete oxidation to Fe³+ (Ce4+ + Fe²+ → Ce³+ + Fe³+). Calculate the weight percent of Cl in the original sample. 2+ FeSO4 (NH4)2SO4 · 6H₂O . Ferrous ammonium sulfate FM 392.13 FeCl2 6H₂O Ferrous chloride FM 234.84 b) A 50.0-mL solution containing Ni²+ and n²+ was treated with 25.0 mL of 0.0452 M EDTA to bind all the metal. The excess unreacted EDTA required 12.4 mL of 0.012 3 M Mg2+ for complete reaction. An excess of the reagent 2,3-dimercapto- 1-propanol was then added to displace the EDTA from zinc. Another 29.2 mL of Mg2+ were required for reaction with the liberated EDTA. Calculate the molarity of Ni²+ and Zn²+ in the original solution. How many millimoles of solute are contained in: (a) 2.95 mL of 0.0789 M KH₂PO4? (b) 0.2011 L of 0.0564 M HgCl₂? (c) 2.56 L of a 47.5 ppm solution of Mg(NO3)2? (d) 79.8 mL of 0.1379 M NH4VO3?
