Question

How will you show that metal oxides are basic in nature? Give an example.

Answer 1

When we add water to metallic oxide, it forms hydroxide, which turns red litmus to blue. That shows it is basic in nature. Example: Magnesium oxide, when dissolved in water, forms magnesium hydroxide that is basic in nature.
$MgO+H_{2}O\to Mg{\left(OH\right)}_2$
