Explain the following in terms of gain or loss of oxygen with two examples each .
(a) Oxidation (b) Reduction

Text Solution

Verified by Experts

(a) Oxidation : The gain of oxygen is called oxidation.
E.g. (i) `2Zn+O_(2)rarr2ZnO`
(ii) `4Al+3O_(2)rarr2Al_(2)O_(3)`
(b) Reduction : The loss of oxygen is called reduction .
E.g. :(i) `Fe_(2)O_(3)+3Crarr2Fe+3CO`
(ii) `PbO_(2)+CrarrPb+CO_(2)`
