(1) The amount of chemical change during electrolysis is proportional to the charge passed.
(2) The charge required to deposit or liberate a mass m is given by Q=Fmz/M, where F is the Faraday constant, z the charge of the ion, and M the relative ionic mass.
These are the modern forms of the laws. Originally, they were stated by Faraday (1834) in a different form:
(1) The amount of chemical change produced is proportional to the quantity of electricity passed.
(2) The amount of chemical change produced in different substances by a fixed quantity of electricity is proportional to the electrochemical equivalent of the substance.
Chemistry
Two laws describing electrolysis:
(1) The amount of chemical change during electrolysis is proportional to the charge passed.
(2) The charge required to deposit or liberate a mass m is given by Q = Fmz/M, where F is the Faraday constant, z the charge of the ion, and M the relative ionic mass.
These are the modern forms of the laws. Originally, they were stated by Michael Faraday in 1834 in a different form:
(1) The amount of chemical change produced is proportional to the quantity of electricity passed.
(2) The amount of chemical change produced in different substances by a fixed quantity of electricity is proportional to the electrochemical equivalent of the substance.
