1. Which is statement is INCORRECT? a. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron. b. Reduction is a process in which an atom gains an electron and therefore decreases (or reduces its oxidation number). c. Oxidation is a process in which an atom gains an electron and therefore increases its oxidation number. d. An electron-donating species which tends to hand over electrons can be referred to as a reducing agent. 2.
