Which precaution will you take while using the methods of distillation and separation by separating funnel?

Answer 1

1. Precautions to be used during distillation:
   1. The apparatus should be set in a proper manner with all the components fitted well.
   2. Never heat the system that is totally closed from the outside atmosphere to prevent an explosion.
   3. Add boiling chips to reduce bumping (rapid boiling causing the liquid to expel out of the container).
   4. Control the rate of heating so as not to overheat to avoid bumping.
2. Precautions to be used while using the separating funnel for separation:
   1. The funnel should be tightly fixed to the stand in an erect position.
   2. The liquid in the funnel should be left undisturbed to allow it to separate.
   3. The stopper should be removed carefully without disturbing the setup.
