What mass of `HNO_(3)` is needed to convert 5g of the iodine into iodic acid according to the reaction
`I_(2)+HNO_(3) to HIO_(3)+NO_(2)+H_(2)O`

A

`12.4 g`

B

`24.8 g`

C

`0.248 g`

D

`49.6 g`

Text Solution

Verified by Experts

The correct Answer is:
A
`{:(1e,+,N^(5+),rarr,N^(4+),),(,,I_(2)^(0),rarr,2I^(5+),+10e),(,,,,,):}`
Meq. Of `HNO_(3)=` Meg. Of `I_(2)`
`(w)/(63//1)xx1000xx=(5)/(254//10)xx1000`
`w=12.4g`
