Question

Give an example for basic oxide.

Answer 1

Definition

• Basic oxides are oxides that react with water to form a base.
• Metallic oxides are basic in nature.

Example:

Magnesium oxide($\mathrm{MgO}$) react with hydrochloric acid($\mathrm{HCl}$) to form magnesium chloride (${\mathrm{MgCl}}_2$) and water(${\mathrm{H}}_2\mathrm{O}$).

$\mathrm{MgO}\left(\mathrm{s}\right)+2\mathrm{HCl}\left(\mathrm{l}\right)\to {\mathrm{MgCl}}_2\left(\mathrm{s}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$
