The quantity of antimony in a sample can be determined by an oxidation-reduction titration with an oxidizing agent. A 5.43 g sample of stibnite, an ore of antimony, is dissolved in hot, concentrated HCI(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 28.0 mL of a 0.110 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. mass of antimony: percentage of antimony: %
