Salt Bridges and Porous Disks

Postby Caroline C 1G » Fri Feb 09, 2018 2:14 pm

Does the material that makes up salt bridges and porous disks affect their ability to transfer ions?

I think when we discuss salt bridges we use them in general terms to mean that the system continues transferring voltage through the circuit, instead of just stopping when the reactant has been fully oxidized. So I think we can assume that no matter what it's made of, it will serve to transfer enough ions to bring the system to equilibrium.

I think that the purpose of the salt bridge and the porous disk is just to transfer charged ions to keep both the solutions in the anode and cathode neutral. I don't think that the material matters because in class, we the ions transferred never affected anything but neutralizing the charge of the solution.
