    An aqueous solution of \[6.3g\]of oxalic acid dihydrate is made up to 250 ml. The volume of \[0.1\text{ }N\text{ }NaOH\] required to completely neutralise \[10\text{ }ml\] of this solution is

    A)  \[40\text{ }ml\]                      

    B)  \[20\text{ }ml\]

    C)  \[10\text{ }ml\]          

    D)  \[\text{4 }ml\]

    Correct Answer: A

    Solution :

    Normality of oxalic acid solution \[=\frac{6.3}{250}\times \frac{1000}{63}=0.4N\] \[{{N}_{1}}{{V}_{1}}={{N}_{2}}{{V}_{2}}\] \[10\times 0.4={{V}_{2}}\times 0.1\] \[{{V}_{2}}=40\,\,ml\]
