Q16. Explain the following in terms of gain or loss of oxygen with two examples each.
a) Oxidation
(b) Reduction
Ans. (a) Oxidation: It is a process in which gain of oxygen takes place or loss of
hydrogen takes place.
e.g., 2Mg(s) + O2(g) _ Burning > 2MgO(s) (Mg is oxidized to Mgo).
2Cu(s) + O2(g) Heat 2 CuO(s) (Cu is oxidised to Cuo)
(b) Reduction: It is a process in which loss of oxygen takes place or gain of
hydrogen takes place.
e.g., CuO(s) + H2(g) - Heat → Cu(s) + H2O(g) (CuO is reduced to form Cu).
ZnO(s) + C(s) - Heat, Zn(s) + CO(g) (ZnO is reduced to Zn)​
