Oxidation $\to$ Addition of oxygen

In general,

Oxidation is the process of addition of oxygen or any electronnegative element or group OR removal of hydrogen or any eletropostive element or group. For example:

a. $2 M g (s)$ + $O_{2} (g)$ $[O] ⟶$ $2 M g O (s)$ (Addition of oxygen)

b.2 $F e C l_{2}$ (aq) + $C l_{2}$ (g) $[O] ⟶$ $2 F e C l_{3}$ (aq) (Addition of electronegative element)

c. $H_{2} S$ (g) + $C l_{2}$ (g) $[O] ⟶$ $2 H C l (g) + S (s)$ (Removal of hydrogen)

d. $K_{2} M n O_{4} (a q)$ + $O_{3} (g)$ + $H_{2} O (l)$ $[O] ⟶$ $K M n O_{4} (a q)$ + $K O H (a q)$ (Removal of electropostive element)
