    When adding 100 ml of \[HCl+35\,\,ml\] of \[NaOH\], the colour of methyl orange in the solution will be

    A)  Yellow

    B)  Red

    C)  Methyl orange is not a suitable indicator

    D)  Can't be predicted

    Correct Answer: B

    Solution :

    As 35 ml of NaOH will neutralize 35 ml of HCl so in the mixture of these solutions the volume of HC1 is much higher, which means the resultant mixture would be acidic in nature. \[HCl\,(aq)+NaOH(aq)NaCl(aq)+{{H}_{2}}O\,(l)\] Hence methyl orange will impart a red colour to the acidic mixture of solutions. Hence, the correct option is (b).
