What is the primary purpose of adding anti-bumping granules to the flask during distillation?

To separate the non-volatile solutes from the solution

To enhance the condensation of vapour

To prevent the solution from boiling violently (correct)

To increase the boiling point of the solvent

What is the primary difference between distillation and sublimation?

Distillation involves the separation of mixtures, while sublimation involves the purification of a single compound

Distillation involves heating, while sublimation involves cooling

Distillation involves the change of state from solid to liquid, while sublimation involves the change of state from solid to vapour

Distillation involves the change of state from liquid to vapour, while sublimation involves the change of state from solid to vapour (correct)

What is the purpose of the thermometer in the distillation apparatus?

To monitor the temperature of the escaping vapour (correct)
