Question
What is the difference between simple distillation and fractional distillation?
Advertisements
Solution
| No. | Simple distillation | Fractional distillation |
| i. | If in a mixture the difference in boiling points of two liquids is appreciable/large, they are separated from each other using simple distillation. | If in a mixture the difference in boiling points of two liquids is not appreciable/large, they are separated from each other using the fractional distillation. |
| ii. | Simple distillation assembly is used. | The fractionating column is fitted in the distillation assembly. |
| e.g. | A mixture of acetone (b.p. 329 K) and water (b.p. 373 K) can be separated by this method. | A mixture of acetone (b.p. 329 K) and methanol (b.p. 337.7 K) can be separated by this method. |
