(i) Name the separation technique used to separate the constituents of the mixture of miscible liquids. Draw a labelled diagram of the process for separating mixture of acetone and water. (ii) List two properties of the mixture of miscible liquids essential for the process. (iii) A simple fractionating column is provided with beads. Give reasons. |

Answer» (i) The separation technique depends upon the boiling temperature difference between the miscible liquids. If they differ in their boiling points by `25^(@)C` or more, the separation can be done by simple distillation. If the difference is less than `25^(@)C`, fractional distillation is used. Acetone (b.p. = `56^(@C`) and water (b.p. = `100^(@)C`) can be separated by simple distillation. (ii) The constituents of the miscible liquids should be volatile in nature. The constituents of the miscible liquids should not react chemically with each other. (iii) The purpose of beads in the fractionating column is to obstruct the upward movement of liquid with higher boiling point. This helps in the separation of the two liquids. |
