Answer:
7..We can define electrolysis as:
The process by which ionic substances are decomposed into simpler substances when an electric current is passed through them.
Electrolysis is used in industry for the production of many metals and non-metals (e.g., aluminium, magnesium, chlorine, and fluorine). Electrolysis is commonly employed for coating one metal with another. The method of coating one metal with another using an electric current is called electroplating.
