(a) What are amphoteric oxides? Give two examples of amphoteric oxides.
(b) Choose the acidic oxides, basic oxides and neutral oxides from the following:
$N a_{2} O : C O_{2}; C O; S O_{2}; M g O; N_{2} O; H_{2} O .$
(c) Which of the following are amphoteric oxides:
$M g O, Z n O, P_{2} O_{3}, A l_{2} O_{3}, N O_{2}$

Please scroll down to see the correct answer and solution guide.

Right Answer is:

SOLUTION

(a)Oxides of metals which have both acidic as well as basic behaviour are known as amphoteric oxides. Such metallic oxides react with acids as well as a base to produce salt and water. Examples of Amphoteric oxides are aluminium oxide and zinc oxide

(b)
Acidic oxide: $C O_{2}, S O_{2}$
Basic oxide: $M g O, N a_{2} O$
Neutral oxide: $H_{2} O, C O, N_{2} O$

(c) $A l_{2} O_{3}, Z n O$
