Correct Order of Oxides in Acidic and Basic Nature

Acidity and basicity are the properties of oxides that depend on their chemical composition and structure. Here is the correct order of oxides in acidic and basic nature:

1. Acidic Oxides:
Acidic oxides are those that react with water to form acids. They are also known as non-metal oxides. The correct order of acidic oxides is:

- B2O3 > CO2 > N2O5

Explanation: B2O3 is the most acidic oxide as it reacts vigorously with water to form boric acid. CO2 is less acidic than B2O3 but still reacts with water to form carbonic acid. N2O5 is the least acidic oxide among these three.

2. Basic Oxides:
Basic oxides are those that react with water to form bases. They are also known as metal oxides. The correct order of basic oxides is:

- CaO > ZnO > K2O

Explanation: CaO is the most basic oxide as it reacts vigorously with water to form calcium hydroxide, which is a strong base. ZnO is less basic than CaO but still reacts with water to form zinc hydroxide. K2O is the least basic oxide among these three.

3. Amphoteric Oxides:
Amphoteric oxides are those that can react with both acids and bases. The correct order of amphoteric oxides is:

- BeO > MgO > Al2O3

Explanation: BeO is the most amphoteric oxide as it can react with both acids and bases. MgO is less amphoteric than BeO but still shows some amphoteric properties. Al2O3 is the least amphoteric oxide among these three.

4. Order of Oxides in Acidic and Basic Nature:
The correct order of oxides in acidic and basic nature is:

- CO2 > B2O3 > Al2O3 (Acidic)
- CaO > ZnO > K2O (Basic)

Explanation: CO2 is more acidic than B2O3 and Al2O3. CaO is more basic than ZnO and K2O.

Conclusion:

The correct order of oxides in acidic and basic nature is important to understand their properties and reactions with other substances. The order of oxides depends on their chemical composition and structure, and it can help in predicting their behavior in different environments.
