Acid Rain MCQs

The term “acid rain” refers to any precipitation—rain, snow, fog, or dew—that contains more acid than regular water and is therefore considered acidic. The usual rain has a pH of approximately 5.6, which is somewhat acidic due to the reaction of carbon dioxide gas with it to generate a mild carbonic acid.Acids such as nitric acid and even sulphuric acid, which are abundant in polluted air, are among the chemicals that contribute to acid rain. Acid rain is created when nitrogen oxides and sulphur oxides react with rainwater, resulting in the formation of these compounds.
