Question
The quantity of antimony in a sample can be determined by an oxidation-reduction titration with an oxidizing agent. A 5.11-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 25.2 mL of a 0.115 M aqueous solution of KBrO3(aq). The unbalanced equation for the reaction is Calculate the amount of antimony in the sample and its percentage in the ore.Explanation / Answer
here is the balanced equation
6H+(aq) + BrO3
