1 " mol of "`IO_(3)^(ɵ)` ions is heated with excess of `I^(ɵ)` ions in the presence of acidic conditions as per the following equation `IO_(3)^(ɵ)+I^(ɵ)toI_(2)` How many moles of acidified bypo solution will be required to react completely with `I_(2)` thus produced?

Answer» Correct Answer - 6
(i) `10e^(-) +2IO_(3)^(-) rarr I_(2), 2I^(-) rarr I_(2) +2e^(-) xx 5`
`2IO_(3)^(-) +10I^(-) rarr 6I_(2)`
2 mol 10 mol 6 mol
(ii) `{:(I_(2)+2S_(2)O_(3)^(2-),rarr S_(4)O_(6)^(2-) +2I^(-)),(1 mol ,1mol):}`
1 mol of `IO_(3)^(-) = 5` mol `5I^(-) -=3` mol of
`I_(2) = 6` mol of `S_(2)O_(3)^(2-)`
