Answer:
Distillable mixtures may contain a solid in a liquid. This method takes advantage of the boiling point of the substances.
In this way, for the distillation to take place correctly, the mixture must be boiled until the boiling point of the solvent is reached, which will then become steam and can be led to a cooled container, in which it will condense and recover its liquidity. On the other hand the solute will remain in the container without alterations; having in both cases pure substances, free of the initial mixture.
