salt bridge

How does the salt bridge allow ion transfer?

[A De Castro 14B 2H]

The salt bridge allows ion transfer between two half reactions by providing an electrical connection within which ions can flow. This keeps both solutions at a neutral state, so electron flow can continue and be measurable through a voltmeter. Salt bridges usually contain an unreactive electrolyte too. Without a salt bridge, electrons produced at the anode will accumulate at the cathode, which will stop the reaction from running.

Salt bridges allow for a circuit so that the cathode doesn't become too saturated with electrons and thus reject electrons. The salt bridge allows a transfer of electrons back to the anode so that the transfer of electrons is continuous.

I think that this video helps to explain the galvanic cell with the salt bridge https://www.youtube.com/watch?v=7b34XYgADlM .

Since electrons are constantly being gained or lost, the solutions of the cathode and anode may gain a charge. If the solutions have a charge, the transferring of electrons will come to a stop. To allow the electrons to continue to be transferred, the salt bridge needs to maintain the solutions neutral.
