Concept explainers
(a)
Interpretation:
The diagrammatic representation of the given electrolytic cell has to be given and the time required for the completion of
Concept Introduction:
- Electrolysis is the process in which the
electric current is used for the initiation of a non-spontaneous reaction. The process is widely used for the separation of elements from a mixture or ore. The process of electrolysis is carried out in an electrolytic cell. Electroplating is one of the important application of electrolysis. In electroplating electric current is used to deposit the metal ions from the solution to the electrode surface. - The amount of electrical charge that is passing through a circuit depends upon the amount and time of the flow of current. The electrical charge is measured in Coulomb.
Where,
- Faradays First law of electrolysis says that the quantity of substance deposited on an electrode is proportional to the charge passed through the solution.
Where,
- Mole is the mass of the substance that is having
Avogadro number of particles. The number of moles of a given substance can be calculated by dividing its weight to molecular weight.

Interpretation:
The diagrammatic representation of the given electrolytic cell has to be given and the time required for the completion of electrolysis has to be calculated.
