What are Oxides? Describe the types of normal oxides with one examples of each.



Normal Oxides:

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

(i) Basic 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.

(ii) Acidic Oxides:

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. 

(iii) Amphitricha Oxides:

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

(iv) Neutral Oxides:

They are neither acidic nor basic. In aqueous solutions, they are neutral to litmus.

E.g. Hydrogen oxide H20, Carbon Monoxide CO
