Question

How sulphur oxide is basic in nature

Answer 1

First of all he major oxides of sulphur are sulphur dioxide and sulphur trioxide and not sulphur oxide.

All non-metallic oxides are acidic in nature because they react with water to produce corresponding acids.

All non-metallic oxides are acidic in nature because they react with water to produce corresponding acids. Sulphur is also a non-metal and its oxide SO_2SO2 produces sulphuric acid (H_2SO_4H2SO4) on reaction with water. 

All non-metallic oxides are acidic in nature because they react with water to produce corresponding acids. Sulphur is also a non-metal and its oxide SO_2SO2 produces sulphuric acid (H_2SO_4H2SO4) on reaction with water. Thus, SO2 is acidic in nature.
