Question

Classify Following Oxides As Neutral, Acidic, Basic Or Amphoteric: $\mathrm{CO},{\mathrm{B}}_2{\mathrm{O}}_3,{\mathrm{SiO}}_2,{\mathrm{CO}}_2,{\mathrm{Al}}_2{\mathrm{O}}_3,{\mathrm{PbO}}_2,\mathrm{Tl}2{\mathrm{O}}_3.$

Answer 1

Types of oxides:

• Depending upon nature and the properties exhibited by compounds oxides are classified into neutral, amphoteric, and basic or acidic oxides.
• An acidic oxide is known as an oxide that when combined with water gives off an acid.
• A basic oxide is basically known as an oxide that when combined with water gives off a base.
• However, when a substance reacts chemically, both as a base or acid it is known as the amphoteric oxide.
• Neutral Oxide is known as the one that neither has an acidic characteristic nor a basic one.

Classification of the given Oxides :

• Acidic oxide: ${\mathrm{B}}_2{\mathrm{O}}_3,{\mathrm{SiO}}_2,{\mathrm{CO}}_2$
• Basic oxide :${\mathrm{Tl}}_2{\mathrm{O}}_3$
• Amphoteric oxide : ${\mathrm{Al}}_2{\mathrm{O}}_3,{\mathrm{PbO}}_2$
• Neutral oxide :$\mathrm{CO}$
