 P: 247 What is the relation between Electrode Potentials and Redox reactions ? Can we determine the relative strength of reduction of a metal by looking just at the electrode potentials ? Here is a particular thing that confuses me : We know that the standard electrode potential of Lithium is -3.05V I know that this implies that the bulk of the following reaction is to the right . (ie Lithium is a very good reducing agent. Li $\longleftrightarrow$ $Li^{+}$ + $e^{-}$ So here is the confusion : 1. What is the electrode potential of this reaction ? Li $\rightarrow$ $Li^{+}$ + $e^{-}$ 2.What is the electrode potential of this reaction ? Li $\leftarrow$ $Li^{+}$ + $e^{-}$ are these going to be exactly the same as -3.05V or would we see a sign flip ? Also, what exactly is a reduction potential and an oxidation potential ? (is there a difference between the two) ?
