    What is the concentration of nitrate ions if equal volumes of 0.1 M \[AgN{{O}_{3}}\] and 0.1 M NaCl are mixed together                 [NCERT 1981; CPMT 1983]

    A)                 0.1 N     

    B)                 0.2 M

    C)                 0.05 M   

    D)                 0.25 M

    Correct Answer: C

    Solution :

                    0.1 M \[AgN{{O}_{3}}\] will react with 0.1 M NaCl to form 0.1 M \[NaN{{O}_{3}}\]. But as the volume is doubled, conc. of \[NO_{3}^{-}=\frac{0.1}{2}=0.05\,M\]
