0.156 gm of an organic compound on heating with fuming `HNO_3` and `AgNO_3` gives 0.235 gm of `Agl`. Calculate the percentage of iodine in the compound.

Text Solution

Verified by Experts

Mass of organic compound, `W = 0.156g`
Mass of `AgI, W_(1) = 0.235g`
`underset(235g)(AgI) -= underset(127h)(I)`
Percentage of iodine `= (127)/(235) xx (W_(1))/(W) xx 100`
`= (127)/(235) xx (0.235)/(0.156) xx 100 = 81.41%`
