How can you figure out which side of the cell diagram will be the cathode and which will be the anode? Is it only based on the whether the Ecell is negative or positive along, or are there other factors?
If it gets oxidized then it is an anode and if it gets reduced then it is a cathode. I like to think "an ox" and "red cat" when working with half reactions and find it easier to draw my cell diagrams with anode to the left and cathode to the right since it's presented like that in the shorthand notation.
