Electrolysis Water Hydrogen Oxygen
Hydrogen and oxygen separation method of water
There is a technique today. If you want to obtain hydrogen and oxygen, you can do it by electrolysis of water. The chemical formula of water is $H_2O $, which contains hydrogen and oxygen.
Put the two electrodes in water and pass a direct current. At the anode, the oxygen ions lose electrons and coalesce to form oxygen to escape. The electrode reaction formula is: $4OH ^ - - 4e ^ - = O_2 ↑ + 2H_2O $. On the side of the cathode, hydrogen ions get electrons and turn into hydrogen gas to float. The electrode reaction formula is: $2H ^ ++ 2e ^ - = H_2 ↑ $.
Looking at this process, under the action of current, the molecules of water break apart and the hydrogen and oxygen are separated. The hydrogen produced is flammable and has a high calorific value, making it a clean energy source; oxygen is beneficial for respiration, combustion and many other things. This method of electrolyzing water to separate hydrogen and oxygen is of great significance in today's energy and chemical industries, and can help the development of the world.
