Solution

(i) $M g O$ is a basic oxide. Basic oxide dissolves in water forming an alkaline solution.
$M g O + H_{2} O \to M g (O H)_{2}$
(ii) $S O_{2}$ is an acidic oxide which dissolves in water to form $H_{2} S O_{3}$ acid.
$S O_{2} + H_{2} O \to H_{2} S O_{3}$
(iii) $A l_{2} O_{3}$ is an amphoteric oxide as it reacts as both acid and base.
(iv) $C O$ is a covalent oxide formed by the sharing of electrons between $C$ and $O .$
