Question

two statements are given — one labelled as Assertion (A) and the other labelled as Reason (R). Select the correct answer to these questions from the codes (A), (B), (C) and (D) as given below.
Assertion (A): Silver oxide (\(\text{Ag}_2\text{O}\)) is an amphoteric oxide.
Reason (R): Metal oxides which react with both acids as well as bases are called amphoteric oxides.

• A. Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
• B. Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
• C. Assertion (A) is true and Reason (R) is false.
• D. Assertion (A) is false and Reason (R) is true.

Answer 1

The Correct Option is A

Step 1: Understanding the Assertion (A):
The assertion states that silver oxide (\( \text{Ag}_2\text{O} \)) is an amphoteric oxide. An amphoteric oxide is a compound that can react with both acids and bases to form salts and water. This means silver oxide can act as a base when reacting with acids and can act as an acid when reacting with bases.

Step 2: Understanding the Reason (R):
The reason explains the concept of amphoteric oxides. It states that amphoteric oxides can react with both acids and bases. This is the standard definition of an amphoteric oxide. Amphoteric behavior is a key property of certain oxides like \( \text{Ag}_2\text{O} \), zinc oxide (ZnO), and aluminum oxide (Al₂O₃). The ability to act as both an acid and a base makes these compounds unique.

Step 3: Connecting Assertion (A) and Reason (R):
- The assertion correctly identifies silver oxide as an amphoteric oxide, which can react with both acids and bases.
- The reason further clarifies the definition of amphoteric oxides, explaining their ability to react with both acids and bases.
- Since the reason defines amphoteric oxides accurately and the assertion is a correct application of this definition, the assertion and reason are directly connected.

Step 4: Conclusion:
Both the assertion and the reason are true, and the reason correctly explains the assertion. Silver oxide (\( \text{Ag}_2\text{O} \)) is indeed an amphoteric oxide, and its behavior aligns with the standard definition of amphoteric oxides.
