The Laws of Electrolysis were formulated by Michael Faraday.
Michael Faraday, a renowned English scientist, conducted extensive experiments to establish the laws that govern electrolytic reactions. His groundbreaking work laid the foundation for our understanding of electrochemistry.
The First Law of Electrolysis relates to the amount of substance produced.
The First Law states that the amount of substance produced or consumed during an electrolytic reaction is directly proportional to the quantity of electricity passed through the solution.
The Second Law of Electrolysis is about the equivalence of different elements.
The Second Law states that the amounts of different substances produced or consumed during electrolysis are directly proportional to their equivalent weights, which are related to their atomic masses.
Faraday’s constant is crucial for calculating the quantity of electricity.
Faraday’s constant, denoted as F, is a key value used to convert the quantity of electricity into the number of moles of substance involved in the electrolytic reaction. It is approximately equal to 96,485.33289 coulombs per mole.
Electrolysis is the process of using electricity to drive a non-spontaneous chemical reaction.
Faraday’s Laws of Electrolysis provide the theoretical framework for understanding and manipulating chemical reactions using electrical energy. Electrolysis finds applications in various fields, including metal refining, electroplating, and the production of industrial chemicals.
