Q

Describe how to separate mixtures using filtration, evaporation and distillation?

A

Filtration = using a sieve or filter paper to allow tiny particles through but block larger ones
Evaporation = heating the solution until the liquid evaporates leaving the solute behind
Distillation = when the two substances have different boiling points which separates the substances
