I probably posted this about 3 times.
So the equation I have in mind is Ecat/red - Eanod/ox=E standard reduction.
I first look at the cathode (more positive E and switch the other one (ox))
In this problem.
Ag+ has the more positive value=cathode (no switch)
Zn2+ has the more negative value=anode (switch)
Giving me: (+0.337)+(+0.763)=+1.1V (which is not the correct answer)
From the reaction, I clearly know that Zn is the cathode and Ag is the anode.
So (-0.763)+(-0.337)=-1.1V <---- correct answer.
@theonlytycrane , I tried PMing you, but I'm not sure how to insert pictures through chat.
In what situations should I use your technique (way 1) and the other one that worked in this case? Maybe I didn't fully grasp your whole post from last time.
I think whenever there is an equation present (like this one) I use the equation to figure out who is the cat/ox. But when there is no equation, I use your way? Thanks.
