Answer:
When metallic oxides react with water they form metallic hydroxides which are basic in nature. To show that these are basic in nature, we should conduct a litmus paper test. In this experiment, we will observe that red litmus turns blue on coming in contact with them. This shows that metallic oxides are basic in nature.

Explanation:
Dissolve metal oxide in water, this will give Hydroxide ions in the solution. Now you can use Litmus Paper or pH paper to check whether the solution is acidic or basic. Litmus paper will turn blue or the pH paper will show the colour for basic solution . This shows that the metal oxide is basic in nature.
