Salt bridge

What does the salt bridge do in the cell diagram?

The salt bridge keeps the two solutions neutral so the systems can exchange electrons. I hope this helps :)

To add on, without the salt bridge, the reaction would quickly reach equilibrium and come to a halt. In this sense, the salt bridge allows the flow of ions to maintain the charges needed for electron transfer to continue.

Just to add on to what other people have said, it is a way to make sure that the charges of the two solutions in the cell are neutral. For example, if you had copper being oxidized to Cu 2+ in one beaker, the anions would move towards that beaker in the salt bridge.

It keeps the 2 solutions neutral so electrons can continue transferring

it allows for the flow of ions as well

The salt bridge neutralizes both solutions in a sense, so they don't quickly reach equilibrium. By "neutralizing," I mean that if a cation was being produced in one solution, the anion portion of the salt in the salt bridge would neutralize this positive charge.
