Question

Assertion (A): Oxides of most of the metals are basic in nature.

Reason (R): All metal oxides dissolve in water forming alkalies.

विकल्प

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true but R is not the correct explanation of A.

• A is true but R is false.

• A is false but R is true.

Answer 1

A is true but R is false.

Explanation:

Oxides of most metals are basic, so assertion (A) is true. However, not all metal oxides dissolve in water to form alkalis; many are insoluble, so reason (R) is false.
