Chile salt peter a soure of `NaNO_(3)` also contains `NalO_(3)`. The `NalO_(3)` can be used as a surece of iodine produced in the following reactions :
Step 1 : `lO_(3)^(-) + 3HSO_(3)^(-) to l^(-) + 3H^(+) + 3SO_(4)^(2-) `
Step 2 : `5l^(-) + lO_(3)^(-) + 6H^(+) to 3l_(2) + 3H_(2)O`
One litre of chile salt peter solution containing amount of same solution is added to the reaction mixture to bring about the second reaction . How many grams of `NaHSO_(3)` are required in step 1 and what additional volume of chile peter must be added in step 2 to bring in complete conversion of `l^(-) " to " l_(2)` ?

Explanation

Meq. of `NaHSO_(3) = " Meq. of " NalO_(3) = N xx V = (5.8)/(198) xx 6 xx 1000 `
`l^(5+) + 6e^(-) to l^(-) " ( For " KlO_(3), " n-factor = 6 ")` .
` :. " Meq. Of " NaHSO_(3) = 175.76`
`W_(NaHSO_(3))/(M//2) xx 1000 = 175.76`
`rArr W_(NaHSO_(3)) = (175.75 xx 104)/(2 xx 1000) = 9.14` gm
Also , Meq. of `l^(-)` formed using n-factor `6 = 175.76`
In step 2, n-factor of `l^(-) ` is 1 and n- factor for `lO_(3)^(-)` is 5
Meq. of `l^(-)` formed using n-factor `1 = (175.76)/6`
Meq. of `NalO_(3) " used in " 2^(nd) " step " = (175.76)/6`
`rArr (5.8)/(198) xx 5 xx V = (175.76)/6`
`V_(NalO_(3)) = 20 ` ml
