Electrolysis of water is the decomposition of water into oxygen and hydrogen gas due to the passage of an electric current. It is also called water splitting.

Answer:

Electrolysis of water is the process of using electricity to decompose water into oxygen and hydrogen gas. Hydrogen gas released in this way can be used as hydrogen fuel, or remixed with the oxygen to create oxyhydrogen gas, which is used in welding and other applications.

Explanation:

Electrolysis of water is the decomposition of water (H

2

O) into oxygen (O

2

) and hydrogen gas (H

2

) due to an electric current being passed through the water.

An electrical power source is connected to two electrodes, or two plates (typically made from some inert metal such as platinum, stainless steel or iridium) which are placed in the water. Hydrogen will appear at the cathode (the negatively charged electrode, where electrons enter the water), and oxygen will appear at the anode (the positively charged electrode). Assuming ideal faradaic efficiency, the amount of hydrogen generated is twice the amount of oxygen, and both are proportional to the total electrical charge conducted by the solution.

Above is the simple setup for electrolysis of water.
