Cell diagram

Postby Samantha Hoegl Roy 2C » Sat Feb 23, 2019 11:29 pm

For the cell diagram notation; is the anodw always left and the cathodw always the part on the right of the expression?
How do I know which part of the reaction to reverse? (For example in 6L.3 e)?)

The anode will generally be on the left, and the cathode will generally be on the right.

If standard reduction potentials are given, you would reverse the oxidation reaction, namely that of the anode.

I think it's safe to say the anode is on the left and the cathode is on the right because that's how it was presented in the lectures. The standard reaction potentials are given as reductions, so which ever one is being oxidized in the actual reaction, needs to be reversed.

So when it is reversed, does the standard reduction potential become negative?
