Question

What is the nature of non-metallic oxides?

Answer 1

Non-metallic oxide:

• Non-metallic oxides are formed when a non-metal reacts with oxygen gas.
• A non-metallic oxide is acidic in nature.
• For example, Carbon dioxide is a non-metallic oxide.
• General reaction for the formation of non-metallic oxide:

$\mathrm{Non}-\mathrm{metal}+\mathrm{Oxygen}\to \mathrm{Non}-\mathrm{metallic}\mathrm{oxide}$

Nature of Non-metallic oxide:

• When non-metallic oxides mix with water, it forms an acid that dissociates to give hydrogen ions, thus they are acidic in nature.
• The nature of non-metallic oxide can be explained with the help of a given reaction.

${\mathrm{CO}}_2\left(\mathrm{g}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\to {\mathrm{H}}_2{\mathrm{CO}}_3\left(\mathrm{aq}\right)$
