Nomenclature of oxides
The names of the oxides of the elements are formed as follows:
For example: Sb 2O 3 – stibium (III) oxide, N 2O 5 – nitrogen (V) oxide.
The main ones are called oxides that react with substances of acidic nature.
Name of the element in the nominal case + (degree state) + oxide
Chemical properties of the main oxides
1 Interaction with acids forming salts and water:
BaO + 2HNO 3 = Ba (NO 3) 2 + H 2O.
2 Interaction with acid oxides forming salts:
CaO + SO 3 = CaSO 4, (SO 3 + H 2O → H 2SO 4).
