  • question_answer
    If \[20ml\] of \[0.4N\,NaOH\] solution completely neutralises \[40ml\] of a dibasic acid. The molarity of the acid solution is [EAMCET 1987]

    A)                 \[0.1M\] 

    B)                 \[0.2M\]

    C)                 \[0.3M\]

    D)                 \[0.4M\]

    Correct Answer: A

    Solution :

              \[20\times 0.4=40\times N\,\text{or }N=0.2\,\text{or}\,M=\frac{0.2}{2}\]\[=0.1\,M\].
