Simple distillation is a procedure by which two liquids with different boiling points can be isolated. It can be used effectively to isolate liquids that have at least fifty degrees difference in their boiling points. If we want to obtain the solvent from a solution, then this process of distillation can be carried out. (7) Water can be obtained from salt water using this method. The solution is heated in the flask until it boils. The steam rises into the Liebig condenser, where it condenses back into water. The salt is left behind in the flask. In hot and arid countries such as Saudi Arabia this sort of technique is used on a much larger scale to obtain pure water for drinking. This process is carried out in a desalination plant.
