(i) Separation by using separating funnel (used for separating two immiscible liquids). The principle is that immiscible liquids separate out in layers depending on their densities. (ii) Sublimation : It is a process by which solid changes directly into gas and vice versa without passing through the liquid state. Ammonium chloride is sublime. (iii) Filtration followed by evaporation or centrifugation followed by evaporation/distillation. (iv) Separation by using separating funnel to separate kerosene oil followed by evaporation or distillation
