metallic oxides
basic oxides
amphoteric oxides
non-metallic oxides
neutral oxides
acidic oxides
amphoteric oxides
react with both alkalis and acids
examples:
Lead (II) oxide — PbO
Aluminium oxide - Al2O
Zinc oxide — ZnO
basic oxides
acts as a base
dissolve in water to form alkaline solutions
will react with acids to form salt and water
most metallic oxides are basic oxides, exceptions are amphoteric
neutral oxides
neither alkaline nor acidic
if soluble in water, will dissolve into a neutral solution
examples:
NO
CO
H2O
acidic oxides
act as an acid
dissolves in water to form acids
will react with alkalis to form salt and water
most non-metallic oxides are acidic oxides, exceptions are neutral
