Answer:
In a chemical reaction, if one substance is oxidised, the other substance must necessarily be reduced. This is because the electrons lost during oxidation are simultaneously gained during reduction and vice versa. ... Thus, oxidation and reduction always occur simultaneously.

Answer:
In a reaction if oxidation of one substance is taking place, then other substance should get reduced because electron lost during oxidation are simultaneously gained during reduction and vice versa.
For example zinc react with copper sulphate to form zinc sulphate and copper.
CuSO
4
+Zn→ZnSO
4
+Cu
Cu+2SO
4
2+
+Zn→Zn+2SO
4
2+
+Cu
Writing the half reaction,
Zn→Zn
2+
+2e
−
(Oxidation)
Cu
2+
+2e
−
→Cu (Reduction)
They occur simultaneously as
Cu
2+
+Zn→Zn
2+
+Cu
Thus, oxidation and reduction always occur simultaneously.
