Faraday's Law Of Electrolysis
What is Faraday's Law Of Electrolysis?
Faraday's laws of electrolysis state that the amount of chemical change produced at an electrode is directly proportional to the quantity of electricity passed through the electrolyte, and that the amounts of different substances deposited or dissolved by the same quantity of electricity are proportional to their equivalent weights. Mathematically, the mass deposited m = (Q × M) / (n × F), where Q is charge, M is molar mass, n is the number of electrons, and F is the Faraday constant (96,485 C/mol). These laws are foundational to electroanalytical chemistry and industrial electroplating.
