Separating mixtures (Right) Evaporation - Separates a soluble solid from a liquid. If the solution is heated, the liquid evaporates leaving the solid behind. Ex) salt water Filtration - Separates an insoluble solid from a liquid. The solid remains in the filter paper and the liquid goes through the paper. Ex) Sand and water Distillation- separates a liquid from a solution of a soluble solid. The solution is heated until the liquid boils. The vapor condensates and collects in another location. Ex) dirty water. Chromatography - Separates different colored dyes. The dyes travel up the chromatography paper. The more soluble dyes move further up than the less soluble ones. Magnetism- Iron filings are magnetic. 1. How can we separate mixtures?
