• # question_answer 38)   Acid rain is known to contain some acids. Name these acids and where from they come in rain.

$C{{O}_{2}}$ is slightly soluble in water forming carbonic acid. $C{{O}_{2}}+{{H}_{2}}O\to {{H}_{2}}C{{O}_{3}}$ The oxides of nitrogen undergo oxidation reaction followed by reaction with water vapours to form nitric acid. $NO+{{O}_{2}}\xrightarrow{{}}2N{{O}_{2}}$ $2N{{O}_{2}}+{{H}_{2}}O\xrightarrow{{}}HN{{O}_{3}}+HN{{O}_{2}}$ The oxidation of $S{{O}_{2}}$ into $S{{O}_{3}}$ in presence of dust particles or metal ions. The $S{{O}_{3}}$ then reacts with water vapours to form${{H}_{2}}S{{O}_{4}}$. $2S{{O}_{2}}+{{O}_{2}}\xrightarrow[or\,metal\,ions]{Dust\,particles}2S{{O}_{3}}$                 $S{{O}_{3}}+{{H}_{2}}O\xrightarrow{{}}{{H}_{2}}S{{O}_{4}}$
