Detailed explanation-1: -Reduction is the loss of oxygen atom from a molecule or the gaining of one or more electrons. A reduction reaction is seen from the point of view of the molecule being reduced, as when one molecule gets reduced another gets oxidised. The full reaction is known as a Redox reaction.
Detailed explanation-2: -Oxidation is the gain of oxygen. Reduction is the loss of oxygen.
Detailed explanation-3: -(b) Reduction: A chemical reaction in which a substance loses oxygen is called reduction. Example: ZnO + C = Zn + CO ( ZnO is reduced to Zn).
Detailed explanation-4: -Oxygen reduction reaction (O2 + 4H+ + 4eā ā 2H2O) The oxygen reduction reaction (ORR) is an essential process in electrochemistry for energy converting on fuel cells.
