Which of the following gases dissolves in water vapour to produce acid rain during rainfall?
Answer Details
Sulphur (IV) oxide gas dissolves in water vapour to produce acid rain during rainfall. When sulphur (IV) oxide gas dissolves in water vapour, it forms sulphurous acid, which is a weak acid. When it rains, this acid is brought down to the earth's surface, causing acid rain. Acid rain can damage buildings, plants, and aquatic life, and it can also make lakes and rivers too acidic for some fish and other aquatic organisms to survive. Therefore, it is important to control the emission of sulphur (IV) oxide gas into the atmosphere.
