When we say that addition of an electropositive element is reduction then why do we not say that removal of an electropositive element will be oxidation?
Rather we say that removal of an electronegative element will be oxidation but!
If we give it a thought then electropositive and electronegative are two different terms that put innocent creatures like me in a confusion...!..:p
