Salt Bridges

[Rayna Irving 2C]

I still don't really understand what a salt bridge does, can someone please explain it?

[Brennan McGurrr 3C]

Salt bridges counteract the movement of the electrons in the cell. Electrons, which have a negative charge flow towards the cathode. In order to keep the solutions neutral, cations must flow toward the cathode and anions must flow away. The same is true bit vice versa for the anode. If there was no salt bridge, the solutions would become charged. This would affect the electron flow.

Hi. A salt bridge's purpose is to keep the solution neutral by ways of ion transfer. Pulling electrons off a metal for example makes it so that there is now positive ions in solution. It gets harder to pull electrons from a positive solution due to electrostatic interactions between the negative charges and positive charges, which would drastically reduce the electrons pulled from the metal. By having a salt bridge, as positive ions enter the solution, negative ions also enter to balance it out. The same happens at the cathode, except positive ions enter an increasingly negative solution.

Salt bridges ensure that redox reactions can continue to occur. Without the salt bridge, electrons would essentially "pile up" in one solution, causing the flow of electrons to stop and pausing the redox reaction. However, with a salt bridge, ions can flow back to the other solution, preventing the pile up of electrons on one side and the redox reaction can continue. Hope this helps!

A salt bridge helps prevent a build up of charge. As electrons flow from the anode to the cathode, the cathode begins to decrease in charge, making its ability to pull electrons weaker. In order to stop this, the salt bride sends an anion from the cathode solution to the anode in order to maintain the charges

In a galvanic cell, the electrons move from anode to cathode. The cathode becomes negatively charged which means electrons would stop moving towards the cathode because like charges repel. In the salt bridge, negatively charged ions move from the cathode solution to the anode solution, which removes the strong negative charge and allows the electrons to continue to move to the cathode.

The salt bridge allows for the electrons to transfer.

Basically , a salt bridge helps prevent an excess build up of charge and helps the cell work better.

[Muskaan Abdul-Sattar]

Salt bridges help to prevent the build-up of charges on either side by allowing the transfer of electrons.

[Taha 2D]

it keeps the solutions neutral by allowing anions and cations to pass

[Brandon Gruender 3F]

Salt bridges allow the transfer of electrons across the cell, which in turn stops one side from building up too much of a charge.

[Talia Dini - 3I]

A salt bridge prevents the build-up of charges. This occurs by anions traveling to the anode and cations traveling to the cathode.

[Moura Girgis 1F]

A salt bridge basically facilitates the transfer of electrons from the anode to the cathode so that neither side has any charge build-up. It ultimately keeps the solution neutral within the galvanic cell.
