Determination of antimony (III) along with potassium bromate:
Reagents: 0.005 M potassium antimonyl tartrate. 25 cm3 of this solution is diluted to 250 ml along with 1 M hydrochloric acid. Standard 0.002 M potassium bromate solution is prepared within water.
Procedure: Take 25.0 cm3 of antimony solution inside the titration cell and titrate along with potassium bromate through setting the applied voltage at +0.2 V vs SCE. Construct the graph as usual and compute the concentration of antimony solution.
