Question

Assertion: The anions in an electrolytic cell migrate to the cathode.
Reason: Positively charged ions are attracted to the negatively charged cathode in an electrolytic cell.
A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
C. Assertion is true but Reason is false.
D. Assertion is false but Reason is true.
E. Both Assertion and Reason are false.

Answer 1

Hint: Anions are those ions which carry negative charge and cathode carries positive charge. An electrolytic cell can be defined as an electrochemical device that uses electrical energy to carry out a non-spontaneous redox reaction.

Complete answer:
Electrolytic cells are used for the electrolysis of certain compounds. This is done by using the flow of electrons to overcome the activation energy barrier of the non-spontaneous redox reaction.
The three primary components of electrolytic cells are:
Cathode which is negatively charged for electrolytic cells, Anode which is positively charged for electrolytic cells and Electrolyte.
Electrolyte provides the medium for the exchange of electrons between the cathode and the anode.
When we apply an electrical current then the positive ions migrate to the cathode while the negative ions will migrate to the anode. As we know the concept that like charges repel each other while unlike attract each other so the positive charge ions are always attracted to the negative charged ions.

So the assertion is wrong but reason is right, thus the option D is true.

Note:
Electrolytic cells are mainly used for electroplating i.e. process of deposition of one metal on another metal. Electroplating is a process that creates a metal coating on a solid substrate through the reduction of cations of that metal by means of a direct electric current. The part to be coated acts as the cathode; the electrolyte is a solution of a salt of the metal to be coated and the anode is usually either a block of that metal or some inert conductive material. The current is provided by an external power supply.
