Welcome to Chem Zipper.com......: Calculate the millimoles of SeO3(2−) in solution on the basis of following data: 70 ml of 60/M solution of KBrO3 was added to SeO3(2−) solution. The bromine evolved was removed by boiling and excess of KBrO3 was back titrated with 12.5 mL of 25/Msolution of NaAsO2. The reactions are given below. I. SeO3(2−) +BrO3(−) + H+→SeO42−+Br2+H2O II. BrO3(−) +AsO2(−) + H2O→Br(−) +AsO4(3−)+ H+
