* Opposite charges attract: Sodium ions carry a positive charge. The negative electrode, also known as the cathode, has a surplus of electrons and thus a negative charge. The opposite charges of the sodium ions and the cathode create an attractive force.
* Electrolysis: During electrolysis, the applied electric potential drives the movement of ions. The positive sodium ions are repelled by the positive anode and attracted towards the negative cathode.
In summary: The attraction between the positively charged sodium ions and the negatively charged cathode is the driving force that pulls sodium ions towards the electrode. This movement is essential in various electrochemical processes, including the production of sodium metal and the functioning of batteries.
