Movement of ions during electrolysis
Nettet13. sep. 2024 · In an electrolytic cell, the battery creates an ‘electron pull’ from its positive pole. This pole is connected to the anode and therefore electrons are pulled away from the anode into the battery. On the cathodic side, the battery produces an electron pressure again to drive the reduction. So in both cases electrons flow from the anode to ...
