Electrodes and Cell Diagrams

Postby Hiseo Lee 2J » Fri Feb 12, 2016 3:18 pm

I am not completely understanding the conceptual part of what's actually going on when we are talking about galvanic cells. Could someone please explain what actually is going on when we are solving the cell potential problems?

I'm a bit confused on what you're confused about, but I'm going to assume you mean solving a question such as "Predict the standard potential of each of the following galvanic cells" and you're given a cell diagram. Basically,a galvanic cell once you properly add up the half reaction's cell potential OR you do "cathode - anode" the number you get must be positive. Hopefully this answered your question.

Galvanic cells are positive cells. The overall charge on a galvanic cell is positive simply because that's the definition of a galvanic cell. Keep in mind that galvanic cells can refer to fuel cells, rocket fuel, a battery cell, or many other names.
