Two miscible liquids A (boiling point 60 °C) and B (boiling point 90 °C) are in a mixture. Suggest a method to separate them, and draw a labelled diagram.
View Answer Hide Answer

Use distillation . The boiling points differ by 30 °C (more than 25 °C), so on heating, liquid A (60 °C) vaporises first, passes through the condenser, cools, and is collected as pure A, while B stays in the flask.
