Activity Description:

Process of evaporation of water in Is Matter Pure - Class 9 Science Experiment

This experiment aims to demonstrate the process of evaporation and how it can be used to separate the components of a mixture, specifically ink (a mixture of dye and water).

By heating the beaker containing water and ink and observing the watch glass placed on its mouth, students will witness the separation of the components through evaporation.

Required Items:

  1. Beaker
  2. Water
  3. Watch glass
  4. Ink (containing dye and water)

Step by Step Procedure:

  1. Take a beaker and fill it to half its volume with water.
  2. Place a watch glass on the mouth of the beaker, ensuring a proper seal.
  3. Add a few drops of ink on the watch glass.
  4. Heat the beaker containing water and ink.
  5. Observe the watch glass during the heating process.
  6. Continue heating until there are no further changes observed on the watch glass.

Experiment Observations:

  1. As the water in the beaker is heated, the process of evaporation occurs.
  2. The water from the ink evaporates, leaving behind the dye component on the watch glass. Upon the completion of the evaporation, there should be a residue of dye on the watch glass.


  • Ensure proper ventilation during the heating process to avoid inhaling any fumes or vapors.
  • Handle the beaker with caution when it’s heated to prevent any accidental burns.
  • Use an appropriate heat source and avoid direct contact with the flame.

Lesson Learnt from Experiment:

The experiment demonstrates that the process of evaporation can be used to separate the components of a mixture. In this case, water evaporates from the ink, leaving the dye behind on the watch glass. This process highlights the concept of separating mixtures based on their individual physical properties.
