    The equivalent conductance at infinite dilution of a weak acid such as HF

    A) can be determined by extrapolation of measurements of dilute solutions of \[HCl,HBr\] and HI

    B) can be determined by measurement of very dilute HF solutions

    C) can be determined from measurements of dilute solutions of \[NaF,NaCl\] and \[HCl\]

    D) is an undefined quantity

    Correct Answer: C

    Solution :

    [c] Kohlrausch Law, \[{{\Lambda }_{eq}}\left( NaF \right)+{{\Lambda }_{eq}}\left( HCl \right)-\] \[{{\Lambda }_{eq}}(NaCl)={{\Lambda }_{eq}}(HF)\]
