Question

Is ${\mathrm{Sb}}_2{\mathrm{O}}_3$ Amphoteric?

Answer 1

Antimony trioxide (${\mathbf{Sb}}_{\mathbf{2}}{\mathbf{O}}_{\mathbf{3}}$) is an amphoteric oxide.

1. Alkaline solution is formed when the amphoteric oxide is dissolved in water.
2. Hydroxide ions are found in alkaline liquids.
3. As a result, aluminum oxide (${\mathbf{Al}}_{\mathbf{2}}{\mathbf{O}}_{\mathbf{3}}$) and hydrochloric acid react to produce aluminum chloride and water.
4. Sodium aluminate (${\mathbf{NaAlO}}_{\mathbf{2}}$) and water are formed from a solution of sodium hydroxide.
5. $\mathbf{ZnO}$, $\mathbf{SnO}$, and $\mathbf{PbO}$ are more typical examples of amphoteric oxides.
6. In Bronsted Lowry's corrosive base hypothesis, amphoteric refers to this.
7. Models include proteins and amino acids, which contain amine and carboxylic corrosive groups, as well as self-ionizable mixtures such as water.
8. Amphoteric metal oxides are those that react with two acids and bases in the same way as they react with bases to give salts and water.
9. ${\mathbf{Sb}}_{\mathbf{2}}{\mathbf{O}}_{\mathbf{3}}$ is considered an amphoteric oxide when it reacts with both acids and bases to form corresponding salts. Antimony(III) oxide is an amphoteric oxide, and when it reacts with sodium hydroxide in a liquid, it forms the meta-antimonate${\mathbf{NaSbO}}_{\mathbf{2}}$, which can be contained as a trihydrate.
10. The related salts are produced by the further breakdown of antimony(III) oxides into concentrated mineral acids, and they are hydrolyzed when diluted with water.
11. The trioxide is oxidized to antimony(V) oxide by the presence of nitric corrosiveness.
12. The oxide is converted to antimony metal when warmed with carbon.

Hence, ${\mathbf{Sb}}_{\mathbf{2}}{\mathbf{O}}_{\mathbf{3}}$ is Amphoteric.
