Question

For an electrolyte $A_x{B}_y$, which of the following is correct for Kohlrausch law ?

• A. $x{\left({\lambda }_{eq}^{\infty }\right)}_{A^{y+}}+y{\left({\lambda }_{eq}^{\infty }\right)}_{B^{x-}}={\Lambda }_m^{\infty }\left(A_x{B}_y\right)$
• B. $x{\left({\lambda }_m^{\infty }\right)}_{A^{y+}}+y{\left({\lambda }_m^{\infty }\right)}_{B^{x-}}={\Lambda }_m^{\infty }\left(A_x{B}_y\right)$
• C. $\frac{x{\left({\lambda }_{eq}^{\infty }\right)}_{A^{y+}}}{x}+\frac{y{\left({\lambda }_{eq}^{\infty }\right)}_{B^{x-}}}{y}={\Lambda }_m^{\infty }\left(A_x{B}_y\right)$
• D. $x{\left({\lambda }_m^{\infty }\right)}_{A^{x+}}+y{\left({\lambda }_m^{\infty }\right)}_{B^{y-}}={\Lambda }_m^{\infty }\left(A_x{B}_y\right)$

Answer 1

Answer: (B)

${\wedge }_w^{\infty }\left(A_x{B}_y\right)=x{\lambda }_m^{\infty }{A}^{y+}+y{\lambda }_m^{\infty }{B}^{x-}$
