Methods for separating mixtures | Eschooltoday

Simple distillation. This method is best for separating a liquid from a solution. In a way, the concept is similar to evaporation, but in this case, the vapor is collected by condensation. For example, if you want to separate water from a salt solution, simple distillation would be great for this. CLICK HERE to see how it works.
