Simple distillation is a laboratory technique used to separate a mixture of two miscible liquids with significantly different boiling points. When the mixture is heated, the component with the lower boiling point vaporizes first, its vapor is condensed, and collected as a separate liquid (distillate). The other options are methods used for different types of separations: Filtration separates solids from liquids/gases, Solvent Extraction separates substances based on differential solubility in immiscible solvents, and Centrifugation separates components of a mixture based on density difference.
Simple distillation is effective for separating miscible liquids with a significant difference in boiling points (typically > 25°C).
Fractional distillation is used when the difference in boiling points is smaller. Azeotropes are mixtures of liquids that boil at a constant temperature and cannot be separated by simple or fractional distillation.
