Experiment/ Activity to Demonstrate The Electrolysis of Water ? ​

Answer 1

Given Data :- Experiment/ Activity to Demonstrate The Electrolysis of Water ?

Solution :-

"Electrolysis of water activity:

• If we have to separate two atoms, we need to have minimum energy. This energy is supported by the battery. The terminal is attached with the battery which can act as a bridge for ion transportation. Therefore, we have to add baking soda to the pure water for this experiment.

Required apparatus:

• Battery, plastic container, Stopwatch, Lemon, Salt, Detergent, test tubes, and Baking soda.

Procedure:

• At the bottom, place thumbtacks so that the points placed in the container can be forwarded up. Make the space between the battery terminals equal.
• Place the container over the thumbtacks of the battery terminals.
• Fill up the container with the distilled water slowly.
• Add a small quantity of baking soda. Hold firmly and then collect the evolved gas using the test tube. This procedure is done for the following combinations also. (Water and salt, Water and lemon juice and finally water and detergent).

Conclusion:

• If we observe three combinations of (Water and salt, Water and lemon juice and finally water and detergent), the baking soda produces a high amount of electricity because it is easily dissociated into its ions."

Answer 2

$\tt { \pmb{\: \underline{To \: Demonstrate \: The \: Electrolysis \: of \: Water}}} : -$

$\bf \: { \pmb{ \colorbox{lavender}{ \blue{Material \: Required}}}} : -$

• One Battery of 9V
• Two Graphite Pencils
• One Beaker
• Tap Water
• Connecting Wires and tape

$\bf \: { \pmb{ \colorbox{lavender}{ \blue{Procedure }}}} : -$

1. Sharpen both ends of both the pencils.
2. Fill the beaker with tap water. Make sure that the contact with the Graphite in the pencils is perfect
3. Secure the wires with tape.
4. Use a piece of Cardboard to hold the pencils in a vertical position.
5. Place the exposed tips of the pencils in the water,such that tips are fully submerged but aren't touching the bottom.
6. The pencil is being used as ELECTRODE here. Now, Wait for 3-4 minutes and observe carefully.

• Small Gas Bubbles will formed near the electrodes.
• The change takes place in the tap water is the Chemical Change.
