According of Kohlrausch law, the limiting value of molar conductivity of an electrolyte `A_(2)B` is

Options

A. `wedge_(A^(+))^(@)+wedge_(A^(+))^(@)-wedge_(B^(-))^(@)`
B. `wedge_(A^(+))^(@)-wedge_(A^(@))`
C. `2 wedge_(A^(+))+1/2 wedge_(A^(+))^(2)+wedge_(B^(-))^(@)`
D. `2 wedge_(A^(+))^(@)+wedge_(B^(-))^(@)`

Answer

D

Explanation

By definition of kohlrausch's law the llimiting value of molar conductivity of an elctrolyte `A_(2)B "is" wedge_(A^(+))^(@) +wedge_(B^(-))^(@)`
