Types Of Electrodes In Electrolysis | Mini Chemistry –
The discharge of ions during electrolysis can be influenced by the types of electrodes used. Some electrodes are inert (do not take part in electrolytic reaction) while other electrodes are reactive (which may influence the ionic
Electrolysis of water – Wikipedia
Electrolysis of water is the decomposition of water into oxygen and hydrogen gas due to the passage of an electric current. This technique can be used to make hydrogen gas, a key component of hydrogen fuel, and breathable oxygen gas, or can mix the two into oxyhydrogen – also usable as fuel, though more
