What is the purpose of the salt bridge in a galvanic cell, and what would happen if the salt bridge wasn't a neutral salt?

The salt bridge is meant to connect the anode and the cathode while maintaining the electrical charge of the interaction.

The salt bridge is there to balance out the charges to keep the electron flow moving within the cell.

The salt bridge is put into place so as the balance out the charges within the cathode and the anode. By doing so you arre able to prolong the transfer of electrons

A salt bridge allows ion transfer so the two solutions stay neutral. Without the salt bridge, e- transfer would stop due to charge buildup.

Since electrons are being transferred from anode to cathode, positive charge is built up in the anode and negative charge in the cathode. The salt bridge allows for ions to pass between solutions and thus maintaining the redox reaction from being slowed.

A salt bridge allows electrons to flow from one side to the other

without the salt bridge, the charges would build up disabling the flow of electrons due to uneven charges between the two half cells of the voltaic cell. The salt bridge monitors the charges on each side, allowing electrons to continue to flow from the anode to the cathode without a buildup of positive charges at the anode and negative charges at the cathode.

If it wasn't a neutral salt, it would not allow for the charges to be balanced.

The salt bridge allows the flow of electrons to continue from the anode to the cathode, while also avoiding disrupting the electrical charges.

Is there an equation or chemical formula we have to write down for the salt bridge? Or do we just say we have a salt bridge or draw it into the cell diagram?

Since the electron flow between the cathode and the anode depends partly on the charge difference between the two solutions in the way that a slightly positive or negative charge may attract or repel the electron and prevent the flow of the electron from the anode to the cathode. This would result in a current not being generated. A salt bridge maintains neutrality of both solutions by providing the positively and negatively charged ions to the solutions to neutralize the positive or negative buildup of charges as electrons move from the anode to the cathode. If the salt wasn't a neutral salt, there would be more of one of the charged ions than the other which would result in an imbalance of charges.

No, there is no equation or formula we need to write down for the salt bridge. It's just important to draw it on the diagram.
