Salt Bridge

Postby Nathan Mariano 2G » Wed Feb 20, 2019 2:44 pm

What is the function of a salt bridge in a galvanic cell? How would the galvanic cell react without a salt bridge?

A salt bridge keeps the solutions of both anodes and cathodes neutral by basically providing opposite charges. This is so that electron transfer will continue. If the salt bridge isn't there, there will be a buildup of electrical charge on one side and the transfer of electrons will stop.

A salt bridge and the porous disk are essentially the same thing; they allow for the ions to travel into each side of the container, whether it be through two separate containers (this would use a salt bridge) or inside the same container (but separated through a porous disk that only allows the ions to travel through). Hope this helps!
