Chile saltpetre, a source of `NaNO_(3)` also contains `NalO_(3)`. The `NalO_(3)` can be used as a source of iodine, produced in the follwng reactions:
`IO_(3)^(-) + 3HSO_(3)^(-) rarr I^(-) + 3H^(+) + 3SO_(4)^(2-)` ....(1)
`5I^(-) + IO_(3)^(-) + 6H^(+) rarr 3I_(2(s)) + 3H_(2)O` ....(2)
One litre of chile salphere soltuion containg `5.08g NaIO_(3)` is treated with stochiometric quanity of `NaHSO_(3)`. Now an additional amount of same solution is added to reactiion mixture to bring about the secound reaction. How many grams of `NaHSO_(3)` are required in step `i` and what additional volume of chile salphetre must be added in step `II` to bring in complete conversion of `I^(-)` to `I_(2)`?

Answer

`9.14g, 200 mL`
