question about standard cell potential

Postby Andy Lechuga 2C » Fri Mar 17, 2017 11:28 am

On the 2013 Final question 3B the formula is E cell= cathode - anode, however shouldn't it be 1.64V - (-1.33)? Can someone tell me why it is not in this form.

Ecell = cathode - anode when talking about standard reduction potentials. The -1.33 is the standard oxidation potential so if you want to use this formula you must make it positive first.
