  • question_answer
    How many ml of 1 (M) \[{{H}_{2}}S{{O}_{4}}\] is required to neutralise 10 ml of 1 (M) NaOH solution            [MP PET 1998; MNR 1982; MP PMT 1987]

    A)                 2.5         

    B)                 5.0

    C)                 10.0       

    D)                 20.0

    Correct Answer: B

    Solution :

               \[({{H}_{2}}S{{O}_{4}})\frac{{{M}_{1}}{{V}_{1}}}{{{n}_{1}}}=\frac{{{M}_{2}}{{V}_{2}}}{{{n}_{2}}}(NaOH)\]                                 \[\frac{1\times {{V}_{1}}}{1}=\frac{1\times 10}{2}\]; \[{{V}_{1}}=5ml\].
