When given a cell diagram such as C(gr) I H2(g) II Cl-(aq) I Cl2(g) I Pt(s), how are we supposed to determine which is the cathode and which is the anode? I read that we need to look at which side is "positive" and which is "negative", but I'm not really sure what that means or how to determine that.
I am also confused on this, but the textbook mentions that if the overall cell potential is positive then the anode will appear on the right of the cell diagram and the cathode will appear on the left. If the cell potential is negative, meaning the overall reaction is unfavorable, the cathode and anode will switch positions on the cell diagram.
