What is the purpose of a salt bridge?

The purpose of a salt bridge is to allow electrons to flow back to the anode after they are transferred to the cathode. This allows a circuit to form and continuous flow of electrons.

The purpose of the salt bridge is to maintain charge balance as the electrons are moving from the anode to the cathode.

A salt bridge in a galvanic cell maintains charge neutrality between the two half cells so that the cell can continue to function. It does this by containing inert ions that can flow to each of the half cells to balance out the built up charge caused by the transfer of electrons.

It makes sure that the flow in the cell continues.

The anions and cations in the salt bridge dissolve in the solutions to maintain a charge balance so that the redox reaction can continue. The video on galvanic cells that Lavelle posted on his website actually really helped me understand this.

A salt bridge helps the two solutions in a Galvanic cell maintain neutrality through ion transfer, thus preventing charge buildup.

It allows redox reaction to take place continuously in a galvanic cell. Without the salt bridge, as electrons go from anode to cathode, the redox reaction would stop due to charge build up.

the purpose of a salt bridge is to allow electrons to move between the anode and cathode without there being an interruption in the flow

Electrons need to go back to anode side to maintain reactions.
