Question

Kohlrausch's law states that at

• A. finite dilution, each ion makes definite contribution to equivalent conductance of an electrolyte, whatever be the nature of the other ion of the electrolyte
• B. infinite dilution, each ion makes definite contribution to equivalent conductance of an electrolyte depending on the nature of the other ion of the electrolyte
• C. infinite dilution, each ion makes definite contribution to conductance of an electrolyte, whatever be the nature of the other ion of the electrolyte
• D. infinite dilution, each ion makes definite contribution to equivalent conductance of an electrolyte, whatever be the nature of the other ion of the electrolyte

Answer 1

Answer: (D)

infinite dilution, each ion makes definite contribution to equivalent conductance of an electrolyte, whatever be the nature of the other ion of the electrolyte

Answer 2

Kohlrausch's law states that "the equivalent conductance of an electrolyte at infinite dilution is equal to the sum of the equivalent conductances of the component ions.
$\, \, \, \, \, \, \, ?_{8}= ?_a+ ?_c$
where, $?_a =$ equivalent conductance of the anion $\, \, \, \, \, ?_c =$ equivalent conductance of the cation Each ion has the same constant ionic conductance at a fixed temperature, no matter of which electrolyte it forms a part.
