In the estimation of sulphur by Carius method, 0.468 g of an organic sulphur compound afforded 0.668 g of barium sulphate. Find out the percentage of sulphur in the given compound.

Text Solution

Verified by Experts

Percentage of sulphur in an organic compound is given by
` % S = ( 32)/(233)xx ( Mass of "BaSO_4 " formed ")/("Mass of compound taken ")xx 100`
`therefore % S = ( 32)/(233) xx (0.668 )/( 0.468 ) xx 100 =19.60`
