1. Solve the following queries (parts a), b), & c)) dealing with volumetric analysis. Make sure you show complete procedures a) Ammonia reacts with hypobromite, OBr, by the reaction: 2NH3 + 30Br→ N₂ + 3Br + 3H₂O What is the molarity of a hypobromite solution if 1.00 mL of the OBr - solution reacts with 1.69 mg of NH3? b) A 0.8040-g sample of an iron ore is dissolved in acid. The iron is then reduced to Fe2+ and titrated with 47.22 mL of 0.02242 M KMnO4 solution. Calculate the results of this analysis in terms of (a) % Fe and (b) % Fe3O4. The reaction is the following one: MnO4 +5Fe²+ + 8H+ → Mn²+ +5Fe³+ + 4H₂O c) A solution of HCIO4 was standardized by dissolving 0.4008 g of primary-standard- grade HgO in a solution of KBr: HgO(s) + 4Br + H₂O → HgBr?¯ + 2OH- The liberated OH consumed 43.75 mL of the acid. Calculate the molar concentration of the HCIO4.
