Vedclass · Answer

(D) The $Carius$ method is the standard analytical technique used for the quantitative estimation of halogens in organic compounds. In this method,a known mass of the organic compound is heated with fuming $HNO_3$ in the presence of $AgNO_3$ in a hard glass tube known as a $Carius$ tube. The halogen present in the compound reacts with $AgNO_3$ to form a precipitate of silver halide $(AgX)$,which is then filtered,washed,dried,and weighed to calculate the percentage of the halogen.

Which one of the following methods can be used to find out the percentage composition of halogen present in an organic compound?
