The quantity of antimony in a sample can be determined by an oxidation-reduction titration with an oxidizing agent. a 7.51-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 37.1 ml of a 0.115 m aqueous solution of kbro3(aq). the unbalanced equation for the reaction is
bro3-(aq)+sb+3(> br-(aq)+sb+5(aq) (unbalanced)
calculate the amount of antimony in the sample and its percentage in the ore.
