Question

How many of the following oxides are amphoteric in nature? N2O3,P2O3,AS2O3,Sb2O3,Bi2O3

Answer 1

Answer:

Explanation:

amphoteric in nature is Sb4O6

Answer 2

How many of the following oxides are amphoteric in nature ? N2O3,P2O3,AS2O3,Sb2O3,Bi2O3

answer : only one and that is As2O3

explanation : amphoteric means, it has acidic as well as basic nature.

furthar more details for it,

generally oxides of metals are basic in nature

oxides of metalloids are amphoteric in nature

and oxides of non metals are acidic in nature.

here N and P are non metals so oxides of these are acidic

As is metalloid so its oxide is amphoteric

Sb and Bi are metals so oxides of these are basic.

Therefore only As2O3 is amphoteric in nature.
