What you electrolises?

Answer 1

Electrolysis is a chemical process that uses an electric current to drive a non-spontaneous reaction, typically to decompose compounds into their elemental components. It is commonly used for the extraction of metals from ores, the production of gases like hydrogen and oxygen from water, and in various electrochemical applications, such as electroplating. The process occurs in an electrolytic cell, where an anode and a cathode are submerged in an electrolyte solution, allowing ions to migrate and facilitate the reaction.
