The quantity of antimony in a sample can be determined by an oxidation-reduction titration with an oxidizing agent. A 5.95 g sample of stibnite, an ore of antimony, is dissolved in hot, concentrated HCl(aq) and passed over a reducing agent so that all the antimony is in the form Sb³*(aq). The Sb³+(aq) is completely oxidized by 25.0 mL of a 0.135 M aqueous solution of KBrO,(aq). The unbalanced equation for the reaction is BrO, (aq) + Sb³+(aq) Br¯(aq) + Sb³+(aq) (unbalanced) Calculate the amount of antimony in the sample and its percentage in the ore.

The iron content of hemoglobin is determined by destroying the hemoglobin molecule and producing small water-soluble ions and molecules. The iron in the aqueous solution is reduced to iron(II) ion and then titrated against potassium permanganate. In the titration, iron(ll) is oxidized to iron(III) and permanganate is reduced to manganese(II) ion. A 5.00-g sample of hemoglobin requires 32.3 mL of a 0.002100 M solution of potassium permanganate. The reaction with permanganate ion is MnO4(aq)+8H+(aq)+5Fe2+(aq)Mn2+(aq)+5Fe3+(aq)+4H2O What is the mass percent of iron in hemoglobin?
