Electrolysis involves the reactions of giving and taking up of electrons. Naturally the amount or quantity of reactions shall depend upon the number of electrons, taken by electrolyte ions or more appropriately passing through the electrolytes.
Faraday, from his experimental analysis observed a relation between the quantity of electrolytes undergoing reaction with the number of electrons or electric current passing through the electrolyte.
The observations are, proposed as Faraday’s Law of electrolysis. They are two in number. First law states about the exact relationship between the amounts of the ions formed or discharged to the amount of electric current bringing about the redox reaction.
The second law compares the relative amounts of various amounts of ions formed or discharged by the passing of same amount of electric current.
