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 KBr0,(aq). The unbalanced equation for the reaction is BrOz (aq) + Sb³+(aq) – Br (aq) + Sb³+(aq) (unbalanced) Calculate the amount of antimony in the sample and its percentage in the ore.
