In the estimation of sulphur by Carius m | Class 11 Chemistry Chapter Organic Chemistry Some Basic Principles and Techniques, Organic Chemistry Some Basic Principles and Techniques NCERT Solutions

Question:

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.

Answer:

Total mass of organic compound = 0.468 g [Given]

Mass of barium sulphate formed = 0.668 g [Given]

1 mol of BaSO4 = 233 g of BaSO4 = 32 g of sulphur

Thus, 0.668 g of BaSO4 contains 32x0.668/233 g of sulphur = 0.0917 g of sulphur

Therefore, percentage of sulphur = 0.0197/0.468 x100 = 19.59 %

Hence, the percentage of sulphur in the given compound is 19.59 %.
