Define oxidation reduction titration with an oxidizing agent

Reference no: EM13545145

The quantity of an antimony in a sample can be determined by and oxidation reduction titration with an oxidizing agent. A 6.35 g sample of stibnite, an ore of antimony, is dissolved in hot, concentrated HCL(aq) and passed over a reducing agent so that all antimony is in the form Sb^3+(aq). The Sb^3+ (aq) is completely oxidized by 34.3 mL of a 0.105 M aqueous solution Kbr0(3) (aq).

The unbalanced reaction is
BrO(3)^- (aq) + Sb^3+ (aq) --> Br^- (aq) + Sb^5+ (aq)

Calculate the amount of antimony in the sample and the % in its ore.
