STEM Kit Electrolysis of Water
1. It is normal to have water inside the product received, and we have carried out a sealing test before shipment.
2. Make sure waiting more than half a minute to ignite to prevent tempering and bursting.
3. Can Not close the gun valve after power on. Be sure to turn off the gun and then turning off the power immediately.
4. Do Not touch the flame because Hydrogen burning is extremely hot.
Electrolysis of water is the decomposition of water into oxygen and hydrogen gas due to the passage of an electric current. The reaction has a standard potential of −1.23 V, meaning it ideally requires a potential difference of 1.23 volts to split water.
This technique can be used to make (hydrogen gas) and breathable oxygen. As hydrogen is an important industrial commodity, by far most industrial methods produce hydrogen from natural gas instead, in the steam reforming process.
How to use?
The sodium hydroxide is first dissolved in water to form a saturated solution.
Pour the liquid into the reactor along the copper tube. The liquid height is about 3/5.
Screw on the copper tube and add more than 2/3 of the water to the adjacent acrylic tube.
Open the gun valve.
Wait for more than half a minute to drain the air inside.
If you need to shut down, be sure to turn off the gun and then turning off the power immediately.
