What is electrolysis?

Electrolysis is a chemical process that uses electrical energy to drive a non-spontaneous reaction, often used to separate elements from their compounds.

What is the main component needed for electrolysis?

The main component needed for electrolysis is an electrolyte, which is a substance that conducts electricity when dissolved in a liquid or molten.

What are the electrodes used in electrolysis?

The two electrodes used in electrolysis are the anode (positive electrode) and the cathode (negative electrode) where oxidation and reduction reactions occur.

What is an example of electrolysis?

An example of electrolysis is the decomposition of water into hydrogen and oxygen gases using an electric current.

How does electrolysis relate to the extraction of metals?

Electrolysis is commonly used in the extraction of metals from their ores, particularly for reactive metals that cannot be extracted by simple reduction methods
