Question

How much electricity does the electrolysis of water uses?

Answer 1

Electrolysis: Electrolysis is the decomposition of a compound using electrical energy.

• The term electrolysis means breaking a compound down by passing an electric current through it.
• It is a non-spontaneous, oxidation- reduction chemical process.
• The main practical applications of electrolysis are: 1. Extraction of Metals 2. Refining of Metals 3. Production of Chemicals 4. Electroplating 5. Electro-cleaning.
• The electrolysis of water under standard conditions requires a minimum of 237 kJ of electrical energy input to dissociate each mole of water. This is the standard Gibbs free energy of water formation..
