Question

In what characteristic property must two liquids differ if a mixture of them is to be separated by fractional distillation

Answer 1

Boiling point

Step-by-step explanation:

If the liquids have different boiling points, you can separate them by distillation.

You must carefully control the temperature, so only the liquid with the lower boiling point evaporates, and you can collect it using a condenser.

The boiling points should differ by at least 40 °C for a simple distillation to give good separation.
