The quantity of antimony in a sample can be determined by an oxidation-reduction titration with an oxidizing agent. A 3.83g 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 43.6mL of a 0.115M aqueous solution of KBrO3(aq). The unbalanced equation for the reaction is BrO3(aq)+Sb3+(aq)Br(aq)+Sb5+(aq)(unbalanced) Calculate the amount of antimony in the sample and its percentage in the ore. mass of antimony: percentage of antimony
