A simple unified explanation of the red-ox and acid-base concepts.

Some classical examples of the habitual physico-chemical processes are studied and a unifying conclusion is reached. In the red-ox processes, the atoms or groups of atoms which gain electrons according to their respective oxidation numbers are oxidizing, i.c. if the bindings are considered pure ionic, and in the acid-base processes the atoms or groups of atoms which only gain electrons according to their formal charge are acids, i.e. if the bindings are considered pure covalent.
