Question

Sodium oxide is an example of:

Answer 1

Metallic oxides:-

• These oxides are basically the crystalline solids that will contain a metal cation as well as an oxide anion.
• They will react with the water for the formation of the bases or with the acids for the formation of the salts.
• These metal oxides will produce Hydroxide ions (${\mathrm{OH}}^{-}$) ions in the aqueous solution and so are known as basic oxides.
• Sodium oxide (${\mathrm{Na}}_2\mathrm{O}$) is a strong and basic oxide.
• It is basic in nature because of the presence of the Oxide ion ${\mathrm{O}}^{2-}$ which is having a very high tendency to form the combination with the Hydrogen ions.
• Sodium oxide is also a white crystalline solid.

Hence, Sodium oxide (${\mathrm{Na}}_2\mathrm{O}$) is an example of metallic oxide.
