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 [itex]\longleftrightarrow[/itex] [itex]Li^{+}[/itex] + [itex]e^{-}[/itex]
So here is the confusion :
1. What is the electrode potential of this reaction ?
Li [itex]\rightarrow[/itex] [itex]Li^{+}[/itex] + [itex]e^{-}[/itex]
2.What is the electrode potential of this reaction ?
Li [itex]\leftarrow[/itex] [itex]Li^{+}[/itex] + [itex]e^{-}[/itex]
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) ?
