Water Electrolysis Demonstration Kit Product overview A compact, handson electrolysis kit designed for classroom and laboratory demonstrations of water decomposition into hydrogen and oxygen. Constructed from environmentally friendly materials, the kit is lightweight and portable, making it suitable for schools, training agencies, and laboratory teaching. Key benefits Clear visual demonstration of electrolysis and the 2 to 1 hydrogen to oxygen ratio, supporting core chemistry lessons. Ready to use with standard 12 V, 1 A DC power supplies for predictable performance. Compact and lightweight for easy handling and storage during classroom rotations or field demonstrations. Durable components made from environmentally friendly materials suitable for repeated educational use. Features and specifications Weight: 200 grams Dimensions: 8.5 x 8.5 x 12 cm Performance: Under a 12 V, 1 A DC supply, the kit typically collects about 20 ml hydrogen and 10 ml oxygen within 3 to 5 minutes, illustrating that each water molecule contains two hydrogen atoms and one oxygen atom. Materials: Environmentally friendly materials, appropriate for educational and laboratory settings. Included components Observing tube x 2 Electrolytic cell x 1 Rubber stopper x 2 Carbon rod with rubber plug x 2 Alligator clip wires x 2 Basic setup and operation 1. Prepare 200 ml clean water, preferably distilled, to improve conductivity. Add a small amount of conductive additive, for example a 10 percent solution of sulfuric acid or sodium hydroxide, according to standard classroom procedures. 2. Pour the prepared solution into the airtight chamber using a funnel. Raise the funnel and gently squeeze the glass section to release trapped air in the tubes while filling. Fill both observation tubes to the . 3. Connect the positive and negative leads of a 12 V, 1 A DC power supply to the bottom electrodes using the alligator clip wires. 4. Turn on the power supply. Bubbles will form immediately in both observation tubes. After about 3 to 5 minutes, the tube attached to the negative electrode will contain about twice the gas volume of the tube attached to the positive electrode, demonstrating the 2 to 1 volume ratio of hydrogen to oxygen. Suitable uses and scenarios Middle school or school chemistry classes for live demonstration of water electrolysis and molecular composition. Laboratory teaching sessions or training agency workshops where visual, repeatable experiments are required. Science clubs and outreach events to illustrate basic electrochemistry principles in a compact, safetohandle setup. Compatibility and performance notes Designed for use with standard 12 V, 1 A DC power supplies. Performance may vary with lower voltage or current. results when using distilled water and an appropriate conductive additive as described in the setup steps. Components are intended for educational demonstration use; consumable parts as needed for continued reliability.
