    The correct order of increasing \[[{{H}_{3}}{{O}^{+}}]\] in the following aqueous solutions is       [UPSEAT 2000]

    A)                 0.01 M H2S <0.01 M H2SO4 < 0.01 M NaCl < 0.01 \[M\,NaN{{O}_{2}}\]

    B)                 0.01 M NaCl <0.01 M NaNO2 < 0.01 M H2S < 0.01 M H2SO4

    C)                 0.01 M NaNO2 <0.01 M NaCl < 0.01 M H2S< 0.01 M H2SO4

    D)                 0.01 M H2S < 0.01 M NaNO2 < 0.01 M NaCl < 0.01 M H2SO4

    Correct Answer: C

    Solution :

               The acidic nature increases in the order.                                 \[NaN{{O}_{2}}<NaCl<{{H}_{2}}S<{{H}_{2}}S{{O}_{4}}\]
