The quantity of antimony in a sample can be determined by an oxidation-reduction titration with an oxidizing agent. A 6.11 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 33.0 mL of a 0.105 M aqueous solution of KBrO, (aq). The unbalanced equation for the reaction is BrO (aq) + Sb¹+ (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:
