An electrolysis of water working model demonstrates how electricity can split water into its two main components, hydrogen and oxygen. This process is a practical example of chemical decomposition and shows how energy can be used to break molecular bonds.

Key Components of the Model:
- Water Container: A transparent container, such as a glass or plastic cup, holds the water.
- Electrolyte: Adding a small amount of salt or baking soda to the water improves conductivity.
- Electrodes: Two conductive materials, like graphite rods (from pencils) or metal wires, act as electrodes. They are connected to the power source.
- Power Source: A battery or DC power supply provides the electricity needed for the reaction.
- Gas Collection: Two test tubes or small inverted bottles collect the gases formed during the process.
How It Works(Electrolysis of water working model):
- Fill the container with water and dissolve a pinch of salt or baking soda to enhance conductivity.
- Place the electrodes in the water and connect them to the power source, ensuring the electrodes are not touching each other.
- Cover the electrodes with inverted test tubes filled with water to capture the gases produced.
- Turn on the power source. Electricity flows through the water, causing it to split into hydrogen (at the negative electrode or cathode) and oxygen (at the positive electrode or anode).
- You’ll observe bubbles forming at the electrodes. Hydrogen is produced in greater quantity (2 parts) than oxygen (1 part), as per the molecular structure of water (H₂O).
Applications and Learning:
- Real-Life Uses: Demonstrates how hydrogen can be produced as a clean fuel and explains the basics of water splitting in energy storage systems.
- Educational Value: Teaches chemical decomposition, energy conversion, and stoichiometry.
This simple, interactive model effectively explains the concept of electrolysis and its role in science and technology.
