This is named as 'ELECTROLYSIS'.
The classic examples are ;-
#1; Decomposition of water , using the 'H' pattern electrolyser. into its compoentn gases of hydrogen and oxygen.
#2; The electrolysis of sodium chloride solution to form chlorine gas and sodium hydroxide, with the liberation of hydrtogen at the other electrode.
#3; The electrolysis of bauxite (aluminium oxide) to form aluminium.

Electrolysis is the process where an electric current is passed through a substance, causing it to break down into its component elements or ions. This process is commonly used in industry for purposes such as metal extraction and water purification. The substance being broken down is called the electrolyte, and the positive and negative electrodes are called the anode and cathode respectively.
A chemical breakdown of a substance with water is called hydrolysis. This reaction involves the breaking of chemical bonds in the substance with the addition of water molecules.
An electrolyte is a substance that conducts electricity when dissolved in water. To determine if a substance is an electrolyte, you can test its ability to conduct electricity in a solution. If the substance allows electric current to flow through the solution, it is likely an electrolyte.
Ionic substances can conduct electricity because they contain charged particles called ions that are free to move. When an ionic substance dissolves in water or melts, the ions become mobile and are able to carry an electric charge, allowing the substance to conduct electricity.
Conductivity in a substance can be determined by measuring its ability to conduct electricity. This can be done using a conductivity meter, which measures the flow of electrical current through the substance. Higher conductivity indicates a greater ability to conduct electricity.
One example of a substance that conducts electricity in its aqueous state but not in its solid state is sulfuric acid. In its aqueous state, sulfuric acid ionizes into ions that are able to carry an electric current, whereas in its solid state it does not have the mobility of ions to conduct electricity.
