When a voltaic cell operates, ions move through the salt bridge.
The salt bridge is a crucial component in a voltaic cell as it allows the flow of ions between the two half-cells, maintaining electrical neutrality.
It completes the circuit for the flow of charge, allowing the oxidation and reduction reactions to proceed smoothly in the anode and cathode, respectively.
The external circuit is where the electrons flow, while the salt bridge facilitates the movement of ions, ensuring that the charge balance is maintained in both half-cells.
