An electrolytic cell is an electrochemical cell in which electric current is used to drive a non-spontaneous chemical reaction, a process known as electrolysis. In this cell, positive and negative ions in the electrolyte migrate towards the respective electrodes when a direct current (D.C) source is applied. The positive ions move towards the cathode (negative electrode) where they gain electrons and are reduced, while negative ions move towards the anode (positive electrode) where they lose electrons and are oxidized. This movement of ionic charges facilitates electrochemical reactions, allowing for various applications such as electroplating and the extraction of metals

How do ions move in an electrolytic cell?
In an electrolytic cell, positive ions migrate towards the negative electrode (cathode) and negative ions move towards the positive electrode (anode) when a direct current (D.C) source is applied
What is electrolytic conduction?
Electrolytic conduction is the movement of ionic charges through the liquid brought by the application of electricity, which allows electrochemical reactions to take place
