Kohlrausch's law states that at:

Options

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

Answer

B

Explanation

According to Kohlrausch's law "At infinite dilution, each ion makes definite contribution to molar conductance of an electrolyte whatever be the nature of the other ion of the electrolyte"
`Lambda_(m)^(oo)=lambda_(+)^(oo)+lambda_(-)^(oo)`
`lambda_(+)^(oo) and lambda_(-)^(oo)` are molar ionic condutance at infinite dilution for cations and anions, respectively.
