Question

Electrolysis of water explaining detail​

Answer 1

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. However, as hydrogen is an important industrial commodity, by far most industrial methods produce hydrogen from natural gas instead, in the steam reforming process.
