Cell Battery Diagram

Postby Chu 3J » Mon Feb 01, 2016 12:07 am

I am still unsure as to how the cell battery works exactly. More specifically, what is the difference between the "interface between phases" and the salt bridge?

I can answer your specific question, so hopefully that helps!

The salt bridge allows the continuation of the movement of electrons and thus the continuation of work. Without the salt bridge, the anode solution would get a very positive charge and the cathode solution would get a very negative charge, thus trying to move more negatively charged electrons into an already negative solution would not work.

The "interface between faces" refers to the separate phases of the same element, as in Cu(s) and Cu(2+), or the inert conductor electrode (Pt) and the two aqueous species (Fe(3+) and Fe(2+)).
