  • question_answer
    \[NaClO\] solution reacts with \[{{H}_{2}}S{{O}_{3}}\] as, \[NaClO+{{H}_{2}}S{{O}_{3}}\to NaCl+{{H}_{2}}S{{O}_{4}}\]. A solution of \[NaClO\] used in the above reaction contained 15g of \[NaClO\] per litre. The normality of the solution would be               [AMU 1999]

    A)                 0.8         

    B)                 0.6

    C)                 0.2         

    D)                 0.33

    Correct Answer: D

    Solution :

                    \[N=\frac{w\times 1000}{eq.\,wt.\times \text{volume}\,\text{in}\,\,ml.}=0.33N\].
