Estimation of halogens: CarisuMethod: A known mass of compound is heated with conc. HNO_(3) in the presence of AgNO_(3) contained in a hard glass tube known as carius tube in a furnce. C and H are oxidised to CO_(2) and H_(2)O . The halogen forms the corresponding AgX. It is filtered , dried , and weighed. Estimation of sulphur: A known mass of compound is heated with fuming HNO_(3) or sodium peroxide (Na_(2)O_(2)) in the presence of BaCl_(2) solution in Carius tube. Sulphur is oxidised to H_(2)SO_(4) and precipitated as BaSO_(4) . It is filerted, dried and weighed. 0.32 gm of an organic substance when treated by Carius method gave 0.466 gm of BaSO_(4) . Calculate the percentage of sulphur in the compound (Ba=137)
