Question

On what factor does the amount of product formed at an electrode depend upon?

Answer 1

Hint: An electrolytic cell utilizes electric current to execute the otherwise non-spontaneous reaction. This cell is composed of two electrodes and an electrolyte. The amount of product formed from the non-spontaneous reaction at an electrode depends upon several factors i.e. nature of electrodes and electrodes.

Complete answer:
 An electrolytic cell utilizes electric current to execute the otherwise non-spontaneous reaction. This cell is composed of two electrodes and electrolytes. These two electrodes are called cathode and anode. A cathode is that electrode where reduction takes place while an anode is that where oxidation takes place. Reduction potential of an electrode describes how easily that species will be reduced. Therefore, we conclude that the time for which electric current is passed through non-spontaneous reaction and reduction potential of an electrode will define how much amount of product formed at an electrode.
Besides, the nature of electrolyte (whether it is strong or weak) also affects the amount of product formed at an electrode.

Additional information:
Oxidation is the process where loss of electrons takes place whereas reduction is the process where gain of electrons takes place. The application of electrolytic cells includes the electrolysis of water for the production of hydrogen and oxygen gas.

Note:
 It is important to note the amount of product formed at an electrode depends upon the time for which electric current is passed through the reaction mixture. The nature of cathode and anode and their reduction potential also affect the amount of product formed from non-spontaneous reactions. Reduction takes place at cathode while oxidation takes place at anode.
