The Acid Rain Problem. Carbon dioxide in the air can dissolve in rain water to form carbonic acid, H 2 CO 3. CO 2 + H 2 O H 2 CO 3. Carbonic acid is a weak acid. It partially ionises to form hydrogen ions. H 2 CO 3 H + + HCO 3 -. The hydrogen ions from carbonic acid give natural rain water a slightly acid pH value of 5.6.
sulphur + oxygen â sulphur dioxide. Non-metal oxides such as sulphur dioxide and nitrogen oxide are responsible for acid rain. They dissolve in the water in the clouds to form acidic solutions.Acid rain damages rocks and buildings, and harms wildlife.ulphur + oxygen â sulphur dioxide.
