Step 1
What is the name of the separating technique used in diagram D?
Answer
The separating technique used in diagram D is fractional distillation. This method allows for the separation of mixtures based on differences in boiling points. In the diagram, the apparatus shown consists of a round-bottomed flask heated to vaporize the mixture, a condenser to cool and collect the distillate, and a receiving vessel for the separated components. This is particularly effective for mixtures of liquids, where each component can be distilled off at its own boiling point.
