Question

In which of the following cells polarization is the major defect?

(A) Voltaic cell

(B) Daniel cell

(C) Leclanche cell

(D) Fuse cell

Answer 1

Hint There are many chemicals used inside of an electrochemical cell. Sometimes there may be some unwanted chemical reactions, which may cause some unwanted results. Those unwanted results are collectively called polarization.

Complete step-by-step answer
There are many chemicals used inside of an electrochemical cell. Sometimes there may be some unwanted chemical reactions, which may cause some unwanted results. Those unwanted results are collectively called polarization. Those chemical reactions result in a deposition of a barrier between the surface of an electrode and an electrolyte.
There is a lot of polarization inside of a Voltaic cell than any other cell due to the chemical reactions happening inside the Voltaic cell.

Hence, the correct answer is option A.

Note: Daniel cell is also the same type of cell as that of Voltaic cell. Actually, the Daniel cell is an improved version of the Voltaic cell. It is structured in a very specific manner so that it reduces the polarization. Hence, Daniel cell is not the answer to the question.
