The quantity of antimony in an ore can be determined by an oxidation-reduction titration with an oxidizing agent. The ore is dissolved in hot, concentrated acid and passed over a reducing agent so that all the antimony is in the form Sb3 (aq). The Sb3 (aq) is completely oxidized by an aqueous solution of BrO3-(aq). Complete and balance the equation for this reaction in acidic solution.
BrO3- + 6H+ + 6 e- --> Br- + 3H2O
