Electrical conductance (or electrical conductivity) is the ability of a solution to conduct an electrical current. By inserting two electrodes into distilled water a direct current does not flow through, but if the solution contains electrolytes the electrical current flows through the salt solutionRead more

Molar Conductivity is defined as the Conductivity of the solution of an electrolyte divided by the Molar concentration of the electrolyte, and so gauges the efficiency with which an allotted electrolyte conducts electricity in solution.

Kohlrausch's law of independent migration of ions states that the limiting molar conductivity of an electrolyte can be represented as the sum individual contributions of its cations & anions. The conductivity of a solution decrease with dilution because less ions are present for conduction.

The two applications of Kohlrausch’s law are, (i) the molar conductivity of weak electrolytes at infinite dilution can be calculated using Kohlrausch’s law. (ii) degree of dissociation of weak electrolyte (like acetic acid) at a given concentration can be calculated.

After his extensive investigations on electrolysis of solutions and melts of electrolytes, Faraday published his results during 1833-34 in the form of the following well known Faraday’s two laws of electrolysis:
(i) First Law: The amount of chemical reaction which occurs at any electrode during electrolysis by a current is proportional to the quantity of electricity passed through the electrolyte (solution or melt).
(ii) Second Law: The amounts of different substances liberated by the same quantity of electricity passing through the electrolytic solution are proportional to their chemical equivalent weights (Atomic Mass of Metal ÷ Number of electrons required to reduce the cation).
In the primary batteries, the reaction occurs only once and after use over a period of time battery becomes dead and cannot be reused again. The most familiar example of this type is the dry cell (known as Leclanche cell after its discoverer) which is used commonly in our transistors and clocks.

These are batteries that can be recharged after use by passing current through the electrodes in the opposite direction, i.e. from the negative terminal to the positive terminal. For example, a lead storage battery that is used in automobiles and inverters can be recharged a limited number of times.

Corrosion is a natural process in which a refined metal is converted to a more chemically stable form, such as oxide, hydroxide, or sulphide. It is the gradual decomposition of materials (usually metals) as a result of chemical and/or electrochemical reactions with their surroundings.
