    \[10\,\,c{{m}^{3}}\] of 0.1 N monobasic acid requires \[15\,\,c{{m}^{3}}\] of sodium hydroxide solution whose normality is

    A)  1.5 N                                    

    B)  0.15 N

    C)  0.066 N                               

    D)  0.66 N

    Correct Answer: C

    Solution :

    Volume of monobasic acid \[=10\text{ }c{{m}^{3}}\] Normality of monobasic acid = 0.1 N Volume of \[NaOH\]solution \[=15\text{ }c{{m}^{3}}\] Normality of \[NaOH\]solution = ?                                 \[{{N}_{1}}{{V}_{1}}={{N}_{2}}{{V}_{2}}\]         (for monobasic acid)               (for \[NaOH\])                 \[10\times 0.1\,N=15\times {{N}_{2}}\]                 \[{{N}_{2}}=\frac{1\,N}{15}=0.066\,\,N\]
