Question

metal hydroxides and metal oxides are called bases explain and support your answer by balanced chemical equation

Answer 1

Metallic oxides are basic in nature because they react with dilute acids to form salt and water. They also react with water to form metal hydroxides which are alkaline in nature because these metal hydroxides release OH- ions in solution.

Answer 2

Answer:

Metallic oxides are basic in nature because they react with dilute acids to form salt and water.

Explanation:

Oxides of elements give hydroxides of the form OH– in aqueous solutions.

This can also be proven by the litmus paper test where metal oxides when reacting with water will form strong bases and turn red litmus paper to blue.
