Lab Water Electrolysis Apparatus Water Electrolysis and Hydrogen and Oxygen Production Chemical Physical Teaching Demonstration Instrument Student Teaching Aid

Specification: Condition: new Type: laboratory water electrolysis unit Package: 1 * Water electrolysis equipment 2 * U-shaped wire Usage and Precautions 1. Lead the water into the container from the water injection port to the 0 mark position. 2. Connect the instrument to a 12V DC stabilized power supply (student power supply, teaching power supply, dry battery), pay attention to the positive and negative terminals, the red is the positive pole, and the black is the negative pole. 3. In order to enhance the conductivity of water, a small amount of dilute sulfuric acid (H2SO4) or sodium hydroxide (NaOH) solution can be used in the water to speed up the production of hydrogen and oxygen. 4. During the experiment, if you need to use the combustion method to verify the presence of hydrogen, please pay attention to the experimental protection to ensure safety. 5. After use, please clean and dry the instrument and store it in a ventilated and dry place. Reminder: This product is not a PEM (Proton Exchange Membrane) electrode water electrolyzer. The electrode of this product is an ordinary metal alloy electrode.

Features

• The instrument consists of a plastic container, an electrode, a gas nozzle, and the like. Our product is also equipped with 2 wires about 40cm/15.7inch in length.
• Under the action of the DC voltage 12V-18V, the oxygen and hydrogen generated in 3-5 minutes (10:20) verifies that the water molecule consists of an oxygen atom and two atoms hydrogen.
• The instrument should be handled with care, do not collide, and store in a cool dry place after use. Keep your eyes as far as possible and wear protective glasses.
• Water electrolysis experimenter allows students to understand the process of generating hydrogen and oxygen after the water is energized.Applicable to school teaching tool, learning display, and collectibles, also will be a great addition to your lab supplies.
• If you encounter any problems, please contact us as soon as possible.We will do our best to meet your needs!
