Normal Oxides are those oxides in which oxygen shows normal oxidation state or valence number—-2
They are four types.
(i) Basic oxides (ii) Acidic Oxide (iii) Amphitricha oxides (iv) Neutral Oxides
Basic Oxides are the normal oxide of metals.
E.g. Na20, PbO, Cao These oxides dissolved in water to give hydroxides and turned litmus blue.
Acidic Oxides are the normal oxides of non-metals. e.g. S02, C02, N02.They react with water to form acids which turn blue litmus red.
These oxides have dual characteristics i.e. acidic as well as basic. They are compounds of oxygen with less electropositive metals. E.g. ZnO
They can react with acids & alkalies to form salt & water
They are neither acidic nor basic. In aqueous solutions, they are neutral to litmus.
E.g. Hydrogen oxide H20, Carbon Monoxide CO
