Methods include: handpicking, sieving, filtration. Separation of Two Immiscible Liquids Separation of a mixture of two immiscible liquids Separation of a mixture of two immiscible liquids is done by using a separating funnel. Applications: To separate a mixture of oil and water, in the extraction of iron from its ore. Centrifugation Centrifugation uses centrifugal force for the separation of two liquids in a mixture. Here, a denser component of the mixture migrates away from the axis, and lighter component migrates towards the axis. Sublimation Sublimation is the transition of a substance from solid phase to gaseous phase without changing into liquid phase. Example : Naphthalene balls undergo sublimation. Chromatography Chr...
