In the electrolytic cell, flow of electrons is from:a)Cathode to anode...
Explanation:
An electrolytic cell is a device that uses electrical current to drive a non-spontaneous redox reaction. The process of electrolysis involves the passing of an electric current through an electrolyte, which causes the ions in the electrolyte to move towards the electrodes, where they undergo chemical reactions.
Flow of electrons:
The flow of electrons in an electrolytic cell is from the anode to the cathode through an internal supply. When a voltage is applied to the electrodes, the anode becomes positively charged and the cathode becomes negatively charged. This causes the positively charged cations in the electrolyte to move towards the negatively charged cathode, while the negatively charged anions move towards the positively charged anode. As the cations reach the cathode, they gain electrons and are reduced, while the anions lose electrons at the anode and are oxidized.
External supply:
While an external supply is required to create the initial potential difference between the electrodes, it does not determine the flow of electrons in the electrolytic cell. The flow of electrons is determined by the relative charges of the electrodes, which are established by the movement of ions in the electrolyte.
Conclusion:
Therefore, option B is the correct answer as the flow of electrons is from the anode to the cathode through an internal supply in an electrolytic cell.

In the electrolytic cell, flow of electrons is from:a)Cathode to anode...
Actually the answer must be (b)
Electrolytic cell consists of non spontaneous reaction outer electric supply must be provided to drive the reaction...
The flow of electrons is always from -ve to +ve
And as electrolytic cell has cathode-ve & anode +ve...the electrons would always flow from cathode to anode BUT through EXTERNAL SUPPLY...
HOPE U GET IT!!!
All the best for exams too.....
