Understanding Metal Oxides Reactivity
Metal oxides exhibit different chemical properties based on their interaction with acids and bases. Some react with acids, some with bases, and some with both.
Defining Oxide Types
The classification depends on their reaction patterns:
- Acidic oxides typically react with bases (e.g., SO2, CO2).
- Basic oxides typically react with acids (e.g., Na2O, CaO).
- Neutral oxides do not react significantly with either acids or bases (e.g., CO, N2O).
- Amphoteric oxides exhibit dual behavior, reacting with both acids and bases.
Identifying Oxides Reacting with Acids and Bases
The question asks for metal oxides that react with both acids and bases. This specific characteristic defines amphoteric oxides.
Example Reactions:
Zinc oxide (ZnO), an amphoteric oxide, reacts with hydrochloric acid (an acid) and sodium hydroxide (a base):
With Acid: $ZnO + 2HCl → ZnCl2 + H2O$
With Base: $ZnO + 2NaOH + H2O → Na2[Zn(OH)4]$
Therefore, metal oxides that react with both acids and bases are called amphoteric oxides.
Correct Answer Identification
Based on the definitions, the correct classification for metal oxides reacting with both acids and bases is Amphoteric oxides.
