\huge\underline\bold\orange{Answer:}

To demonstrate the electrolysis of water :

Materials Required : A battery of 9V (six cells of 1.5 V),two graphite pencils, a beaker,tap water, connecting wires and tape.

Procedure : Sharpen Both ends of both the pencil. Fill the beaker with tap water. Make a simple circuit. Secure the wire with tapes. Use a piece of cardboard to hold the pencils in a vertical position. Place the exposed tips of the pencil in the water,such that tips are fully submerged but are not touching the bottom. Now wait for 3-4 minutes.

Small gas bubbles are seen to be getting formed near the electrodes. We can call this change,taking place in tap water,a chemical change.
