    25 ml of a solution of barium hydroxide on titration with a 0.1 molar solution of hydrochloric acid gave a litre value of 35 ml. The molarity  of  barium hydroxide solution was  

    A) 0.07                 

    B) 0.14         

    C) 0.28                             

    D) 0.35         

    Correct Answer: A

    Solution :

    For HCl \[M=N\,\,=\,\,0.1\] \[{{N}_{1}}{{V}_{1}}={{N}_{2}}{{V}_{2}};\,\,25\times {{N}_{1}}=0.1\times 35\] \[{{N}_{1}}=\frac{0.1\times 35}{25};\,\,\,\,\,\,\therefore \,\,M=\frac{0.1\times 35}{25\times 2}\,\,=\,\,0.07.\]
