    Which of he following oxides finally dissolve in water to cause acid rain?

    A)  \[NO,N{{O}_{2}}\]                         

    B)  \[N{{O}_{2}},S{{O}_{2}}\]

    C)  \[N{{O}_{3}},S{{O}_{3}}\]                           

    D)  \[{{N}_{2}}{{O}_{5}},S{{O}_{3}}\]

    Correct Answer: B

    Solution :

                     Acid rain is a popular term refering to the deposition of wet part (rain, snow, fog, cloud water) and dry part (acidifying particles and gases/acidic components). Oxides of nitrogen and sulphur are the main components that cause acid rain usually dioxides are responsible for acid rain.           eg,          \[N{{O}_{2}}+{{H}_{2}}O\xrightarrow{{}}HN{{O}_{3}}\]                \[\,S{{O}_{2}}\xrightarrow{O}S{{O}_{3}}+{{H}_{2}}O\xrightarrow{{}}{{H}_{2}}S{{O}_{4}}\]
