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.
Best Answer: Carbon dioxide gas does not allow the heat and infra red rays to get out of the earth's atmosphere. All things on earth absorbs heat radiations from the sun and at the same time emit radiations in the form of infrared rays. Carbon dioxide is not a pollutant by itself. But excess of it is harmful to us as it traps heat and causes green house effect. Excess heat causes melting of glaciers and polar ice caps.
