Water Electrolyzer, Micro Gas Generator, Chemical Equipment Teaching Instrument Water Electrolysis Device Complete Set of High Concentration Experiment Demonstrator Demonstrator

Name: Water Electrolysis ExperimenterSize: bottom length 90* bottom width 551 total height 180mmMaterial: Plastic + MetalWeight: 90gInstructions1. Unplug the 2 rubber tubes from the gas outlet, and introduce water into the container from the water injection port to the 0 mark position, and then press the rubber tube again. (Use drainage method to collect gas, otherwise it is easy to mix in air)2. Connect the instrument to a 9V DC stabilized power supply (student power supply, teaching power supply, dry batteries are all acceptable)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, 7-8% sodium hydroxide (NaOH) solution must be added to the water to speed up the production of hydrogen and oxygen, otherwise the experimental effect will not be seen.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.

• Use: Demonstrate the process of water electrolysis and hydrogen and oxygen production in the chemical class middle school ..
• Construction: scale tube (scale value 1 ml), alloy electrode, plastic basis ..
• Performance: Under the effect of 12 V-18 V DC voltage, the ratio of oxygen and hydrogen generates in 3-5 minutes (10.20) whether the water molecule is composed of an oxygen atom and two hydrogen atoms ..
• Make sure that: In the experiment, 10% sulfururs or sodium hydroxide (salt) in water can be increased in the direction of leadership .. Effect
• Note: Keep your eyes away as far as possible and bring safety glasses.
