0.1170 gm of an organic compound on heat...

0.1170 gm of an organic compound on heating with conc. `HNO_3` and silver nitrate in Carius furnace gave 0.42 gm of `AgCl`. Find the percentage of chlorine in the compound.

Text Solution

Verified by Experts

Mass of organic compound, `W = 0.1170g`
Mass of `AgCI, W_(1) = 0.42g`
`underset(143.5g)(AgCI) -= underset(35.5g)(CI)`
Percentage of chlorine `= (35.5)/(143.5) xx (W_(1))/(W) xx 100`
`= (35.5)/(143.5) xx (0.42)/(0.1170) xx 100 = 88.80%`
Halogens can also be estimated by Schiff's and Piria method.
