Question

In a distillation experiment, Provide reasons for any discrepancies between the initial volume of the liquid mixture (20ml) and the sum of the total final volume (18.4ml). Take into account water’s property of solvent.

Answer 1

The densities change, the mass would be the same, but density will not.

Step-by-step explanation:

As water is a great solvent, when a solute is added, it will change the mass of the mixture, but the volume will change very little. Thus, when they are separated, the densities are expected to change, in this case, an increase, so the mass is the same but the volume is less.
