What is the name of the chemical compound which is formed when sulphur dioxide is treated with water?
(a) Name the acid formed when sulphur dioxide dissolves in water.
(b) Name the gas released when sodium carbonate is added to a solution of sulphur dioxide.
The name of the product formed in the reaction of sulphur and Oxygen is sulphur dioxide gas. When sulphur dioxide is dissolved in water, sulphurous acid is formed. The sulphurous acid turns blue litmus paper to red. Generally, oxides of non-metals are acidic in nature.
