In Carius method for the quantitative estimation of sulphur. it is estimated by__________.

A$$BaS$$
B$$CaSO_4$$
C$$BaSO_4$$
Correct Answer
D$$BaCl_2$$

Solution

Sulphur present in any organic compound is also estimated by Carius method.
Sulphur present in any organic compound is oxidized to sulphuric acid by digesting with fuming nitric acid. Sulphuric acid so formed is then quantitatively precipitated as barium sulphate by the addition of excess barium chloride. The precipitate of barium sulphate is filtered, washed, dried and weighed.
