Answer:Here are some common separation techniques:1. Filtration – used to separate an insoluble solid from a liquid (e.g., sand and water).2. Evaporation – used to separate a soluble solid from a liquid (e.g., salt from saltwater).3. Distillation – used to separate mixtures based on differences in boiling points (e.g., alcohol and water).4. Decantation – used to separate liquid from sediment or two immiscible liquids (e.g., oil and water).5. Magnetism – used to separate magnetic materials from non-magnetic ones (e.g., iron filings from sand).6. Chromatography – used to separate substances based on their movement through a medium (e.g., ink or dye components).7. Centrifugation – used to separate substances of different densities using high-speed spinning (e.g., blood components).
