(a) Interpretation: The element experiencing oxidation or reduction, the species being oxidized or reduced and the change in oxidation number are to be stated. Concept introduction: A species gain or loses electrons to form anions or cations respectively. If an atom loses an electron, the atom is said to be oxidized and the process is called oxidation. Similarly, if the atom gains electrons it is said to be reduced and the process is called reduction. To keep a track on the loss or gain of an electron, a number is assigned in the form of oxidation number.
