Question

During electrolysis, cations move towards the positive terminal.
(A) True
(B) False

Answer 1

Hint: The term electrolysis was given by Michael Faraday in the 19th century. It is the process that involves the study of chemical reactions to obtain elements in their pure form. In the modern era, it is a very commercial method used in industries.

Complete answer:
Electrolysis is the process of breaking down ionic compounds into their constituent elements via passing electric current through the compound in their liquid state. The cations that are produced in the solution get reduced at the cathode and anions formed, they get oxidized at the anode. In this whole process of electrolysis, the interchange of ions and atoms occurs due to the addition or removal of electrons from the external circuit. In simple terms, when you pass the current, cations move to the cathode side which is the negative terminal and take electrons it and then they get discharged into the neutral atom. If the neutral atom is solid, it gets deposited on the cathode and if it is gas, it moves upwards. This process is called the reduction process and the cation is reduced at the cathode. At the same time, the anions gave up their extra electrons to the anode which is the positive terminal, and got oxidized to form neutral atoms at the anode. The Electrons released by the anions travel through the circuit and reach the cathode. In this way, the circuit gets completed. The number of ions that get discharged in the solution is given by faraday’s law of electrolysis. He gave two laws that summarized the amount of reaction.
Hence, the above statement is false and option (B) is correct.

Additional Information:
Nucleophilic substitution reactions are those reactions in which a nucleophile that is rich in electrons attacks a positively charged electrophile and replaces the leaving group from the compound. It is a three-step process. It is generally of two types $S{N_{1\,}}\,$ and $S{N_2}$

Note:
There are several factors on which the electrolysis depends, these are Nature and state of electrolytes. Electrolysis has a vast application in the industry. It is used in the metallurgy of alkali and alkaline earth metals, purification of metals, and manufacturing of gases.
