E- Transfer Diagram

Postby JennaMinami1I » Sat Feb 04, 2017 8:24 pm

I was wondering why there is no salt bridge/porous disk in the diagram for electrolysis. Is it because there is already something that is transferring ions (the electron current). Do Ion-selective electrode redox reactions also not have a salt bridge/porous disk, because the electrode helps drive the concentration?

(Diagram is on pg. 54 of the course reader)

Thank you!

Hello Jenna,

The reason why there is no salt bridge is because this is all done in a single beaker. Since they are so close, they can just transfer the electrons back and forth between themselves without the aid of a salt bridge.
