Question

Some of the metallic oxides are known as basic oxides.

• A. True
• B. False

Answer 1

The correct option is A True

A basic oxide is an oxide that when combined with water gives a base. Metallic oxides react with dilute acids to form salt and water. Hence, they are basic in nature. They also react with water to form metal hydroxides that are alkaline.
