Question

Which of the following scientists stated that the equivalent conductivity of an electrolyte at infinite dilution is equal to the sum of the conductances of the ions and cations?

(a) Svante Arrhenius

(b) Friedrich Kohlrausch

(c) Hermann Kolbe

(d) Antoine Lavoisier

This question was addressed to me in class test.

This is a very interesting question from Conductance of Electrolytic Solutions topic in portion Electrochemistry of Chemistry – Class 12

Answer 1

Correct answer is (b) Friedrich Kohlrausch

To explain I would say: Friedrich Kohlrausch was a German scientist who conducted research on the conductive properties of electrolytes. He stated that “at infinite dilution, each ion of an electrolyte contributes a characteristic ionic conductance towards equivalent conductance of electrolyte which is independent of the nature of the other ion present in the solution”.
