Detection Of Halogens
In Carius method for estimation of halogens, an organic compound is heated with fuming HNO3 and AgNO3 in a sealed tube. The purpose of AgNO3 is to:
Select the correct option:
Solution
Precipitate halide ions as AgX
In Carius estimation, halogen in the organic compound is converted to halide ions under strongly oxidizing conditions. Silver nitrate traps these halides as insoluble silver halides (AgCl, AgBr, AgI), which can be weighed for quantitative estimation.
