Question
A solution containing bromate ions (Br03) is reacted with excess iodide ions (1) producing iodine (I2). The evolved iodine is then
titrated with standard thiosulfate (S203²) solution. The pertinent balanced reactions are given below:
Broz + 61 + 6H* 2 Br + 312 + 3H20
12 + 2S203? 2 21 + S4062
Which of the following stoichiometric relationships between Brog and S2032 is correct?
#mmol Bro3 = 3/2 (#mmol S,032
#mmol Bro3 = 1/6 (#mmol S2032)
#mmol Bro3 = 1/2 (#mmol S,0,2)
3(#mmol Br03) =2 (#mmol S2032)
