NEET 2010 Chemistry question
Which of the following expressions correctly represents the equivalent conductance at infinite dilution of . Given that and are the equivalent conductances at infinite dilution of the respective ions?
Answer: (2)
Solution
By Kohlrausch's law, at infinite dilution each ion contributes independently. For equivalent conductances, one equivalent of the salt gives one equivalent of cations and one equivalent of anions, so \circ_{eq}4)_3)\circ_{eq}$(Al^{3+}) +
