Question

Faraday’s laws of electrolysis are related to the:
(a) the atomic no. of the cation
(b) the atomic no. of anion
(c) the equivalent weight of the electrolyte
(d) the speed of the cation

Answer 1

Michael Faraday has done detailed studies on the electrolysis of electrolyte solutions and melts. He was the first physicist to represent the quantitative dimensions of the Electrolysis Laws. He proposed two laws to explain the quantitative aspects of the popularly known electrolysis as the electrolysis laws of Faraday, namely the first law of electrolysis and the second law of electrolysis.

Complete answer:
Faraday's First law of Electrolysis:
It is one of electrolysis' chief laws. During electrolysis, it states that the amount of chemical reaction that happens at each electrode under the influence of electrical energy is equal to the amount of electricity that passes through the electrolyte.
Faraday's laws of electrolysis states that 96500 coulombs of charge are needed to deposit one gm equivalent of an element at electrode. So, it is related to the equivalent mass of electrolyte.
An electrolyte is a substance which, when dissolved in a polar solvent, produces an electrically conductive solution, such as water. The dissolved electrolyte is separated into cations and anions, which uniformly spread through the solvent. Such a solution is electrically neutral.
If an electrical potential is applied to such a solution, the solution's cations are drawn to the electrode which has an excess of electrons while the anions are drawn to the electrode which has an electron deficit. Inside the solution the motion of anions and cations in opposite directions corresponds to a current.
Equivalent weight is known as the mass of one equivalent, i.e. the mass of a substance taken under consideration which will combine with or displace a definite quantity of another substance in a chemical reaction. For an element the equivalent weight is nothing but the mass which combines with or displaces 1.008 gram of hydrogen or 8.0 gram of oxygen or 35.5 gram of chlorine. It is also known as gram equivalents.

Hence, option (c) is correct.

Note: Electrolysis is a method in chemistry and engineering that uses direct electric current to trigger an otherwise non-spontaneous chemical reaction. Electrolysis is important commercially as a stage of extracting elements from naturally occurring sources such as ores using an electrolyte cell.
