प्रश्न

An electrolysis experiment is stopped and the battery terminals are reversed.

पर्याय

  • The electrolysis will stop

  • The rate of liberation of material at the electrodes will increase

  • The rate of liberation of material will remain the same

  • Heat will be produced at a greater rate

उत्तर

The rate of liberation of material will remain the same

 

In an electrolytic cell, both the electrodes are made of the same material. Thus, on reversing the  terminals of the battery, the direction of the flow of charges will be reversed, but the rate of the electrolysis will remain the same.
