Distillation
Simple A separation technique which involves a solution being heated so that the solvent evaporates before being cooled to form a pure liquid. separates a Is the liquid in which a solute dissolves. from a solution using both evaporation and condensation 鈥 the change of state as gas cools and forms a liquid.
Simple distillation works because the dissolved Is the substance that dissolves in a solvent. has a much higher boiling point than the solvent. As the solution is heated, the solvent evaporates. This gas moves away, cools and condenses 鈥 this liquid is called the distillate. The remaining solution becomes more concentrated as the amount of solvent decreases.
