Halogen Estimation
Easychemistry
In Carius method for halogen estimation, the precipitate formed is:
Select the correct option:
Solution
Incorrect! Answer:
AgX
The Carius Method estimates the halogen content in an organic compound.
- Procedure: A known mass of the compound is heated with fuming Nitric acid (HNO3) and Silver nitrate (AgNO3) in a hard glass tube (Carius tube).
- Mechanism: The carbon and hydrogen are oxidized to CO2 and H_2_O while the halogen is converted into an insoluble Silver Halide (AgX) precipitate.
- Result: The precipitate is filtered, washed, dried, and weighed. The percentage of halogen is then calculated from the mass of AgX obtained.
