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

Assertion (A) is true. Silver oxide (\( \text{Ag}_2\text{O} \)) is an amphoteric oxide. Amphoteric oxides can react with both acids and bases.

Reason (R) is also true and correctly defines amphoteric oxides. The definition given in (R) is the standard definition of an amphoteric oxide. Therefore, (A) is the correct answer.
