Get your own distilled water in Separation of Substances – Class 6 Science Experiment

Chapter Name: Separation of Substances

Activity Name: Get your own distilled water in Separation of Substances

Activity Description:

Required Items:

1. Conical flask (2)
2. Corks with holes (2)
3. Glass tubes (2)
4. Plastic tube
5. Burner
6. Water

Step by Step Procedure:

1. Fill one of the conical flasks with water.
2. Close the flask with a cork that has a hole in it.
3. Insert a glass tube through the hole in the cork.
4. Take the second conical flask and insert another glass tube through its cork.
5. Connect both glass tubes with a plastic tube.
6. Place the conical flask containing water on a heat-resistant surface.
7. Light the burner and heat the flask containing water gently.
8. As the water gets heated, it will start to evaporate and form water vapor.
9. The water vapor will travel through the glass tube connected to the first conical flask and enter the second conical flask through the glass tube connected to it.
10. Allow some time for the water vapor to cool down and condense in the second conical flask.
11. The water collected in the second conical flask is distilled water, which is free from impurities.

Experiment Observations:

• Initially, the water in the first conical flask starts to boil and produce water vapor.
• The water vapor travels through the glass tube and enters the second conical flask.
• Over time, the water vapor condenses inside the second conical flask, forming distilled water.

Precautions:

• Handle the burner with care and ensure that it is placed on a stable surface to prevent accidents.
• Be cautious while heating the flask to avoid any splashing of boiling water.
• Use heat-resistant gloves or tongs while handling the hot apparatus.
• Make sure the glass tubes are securely inserted into the corks to prevent any leakage.
• Ensure that the plastic tube is tightly connected to both glass tubes to maintain a continuous pathway for the water vapor.

Lesson Learnt from Experiment:

This experiment demonstrates the process of separating substances through distillation. It shows that by heating a liquid (water in this case) and collecting the resulting vapor, it is possible to obtain a purer form of the substance.

Distillation is an effective method for obtaining distilled water, as it allows the separation of impurities from the original liquid.
