JEE Main & Advanced AIEEE Solved Paper-2007

  • question_answer
    The equivalent conductances of two strong electrolytes at infinite dilution in\[\frac{1}{3}\] (where ions move freely through a solution) at\[\frac{1}{2}\]are given below \[\frac{1}{6}\] \[\frac{1}{4}\] What additional information/quantity one needs to calculate\[I,\]of an aqueous solution of acetic acid?       AIEEE  Solved  Paper-2007

    A)  \[\frac{g\sin \theta }{1+I/M{{R}^{2}}}\] of\[\frac{g\sin \theta }{1+M{{R}^{2}}/I}\]

    B)  \[\frac{g\sin \theta }{1-I/M{{R}^{2}}}\] of\[\frac{g\sin \theta }{1-M{{R}^{2}}/I}\]

    C)  The limiting equivalent conductance of \[60{}^\circ \]

    D)  \[\frac{\lambda }{6}\]of chloroacetic acid\[\lambda \]

    Correct Answer: A

    Solution :

    We know from Kohlrausch's law, \[\lambda _{C{{H}_{3}}COOH}^{o}=\lambda _{C{{h}_{3}}COONa}^{o}+\lambda _{HCl}^{o}-\lambda _{NaCl}^{o}\]
