Science homework help? Help with my science homework? Decantation Definition Decantation is the process of separation of liquid from solid and other immiscible (non-mixing) liquids, by removing the liquid layer at the top from the layer of solid or liquid below. The process of separating smaller particles from bigger ones by passing them through a sieve is called sieving. IV. A utensil of wire mesh or closely perforated metal or plastic, used for straining, sifting, ricing, or puréeing. complexes, liquid crystals, glassy state In rare cases, sensitivity to salicylate can cause symptoms of anaphylactic shock.
