OXIDATION-REDUCTION

2. DEFINITIONS. Oxidation: Loss of electrons.Reduction: Gain of electrons.Reductant: Species that loses electrons.Oxidant: Species that gains electrons.Valence: the electrical charge an atom would acquire if it formed ions in aqueous solution.. 3. RULES FOR ASSIGNMENT OF VALENCES. 1) The valence

OXIDATION – REDUCTION

OXIDATION – REDUCTION . Oxidation-Reduction Reactions. The term oxidation was originally used to describe reactions in which an element combines with oxygen. Example: The reaction between magnesium metal and oxygen to form magnesium oxide involves the oxidation of magnesium.
