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

  • question_answer
    1.0 gm of pure calcium carbonate was found to require 50 ml of dilute \[HCl\]for complete reaction. The strength of the \[HCl\] solution is given by                [CPMT 1986]

    A)                 4 N         

    B)                 2 N

    C)                 0.4 N     

    D)                 0.2 N

    Correct Answer: C

    Solution :

           M.eq. of HCl = M.eq. of \[CaC{{O}_{3}}\]                 \[N\times 50=\frac{1}{50}\times 1000\] ;  \[N=\frac{1\times 1000}{50\times 50}=0.4N\]
