JEE Main & Advanced Chemistry Solutions / विलयन Question Bank Method of expressing concentration of solution

  • question_answer
    A 5 molar solution of \[{{H}_{2}}S{{O}_{4}}\] is diluted from 1 litre to 10 litres. What is the normality of the solution    [AFMC 2005]

    A)                 0.25 N   

    B)                 1 N

    C)                 2 N         

    D)                 7 N

    Correct Answer: A

    Solution :

               \[{{M}_{1}}{{V}_{1}}={{M}_{2}}{{V}_{2}}\] i.e. \[5\times 1={{M}_{2}}\times 10\Rightarrow {{M}_{2}}=0.5\]                                 Normality of the solution \[=\frac{0.5}{2}=0.25.\]
