First law
What did Faraday conclude based on his electrochemical experiments?
Electrochemistry
Faraday concluded after several experiments on electrical current in non-spontaneous process, the mass of the products yielded on the electrodes was proportional to the value of current supplied to the cell, the length of time the current existed, and the molar mass of the substance analyzed. In other words, the amount of a substance deposited on each electrode of an electrolytic cell is directly proportional to the quantity of electricity passed through the cell. Below is a simplified equation of Faraday's first law: formula_7 Where "m" is the mass of the substance produced at the electrode (in grams), "Q" is the total electric charge that passed through the solution (in coulombs), "n" is the valence number of the substance as an ion in solution (electrons per ion), "M" is the molar mass of the substance (in grams per mole).
