Question

Molar conductivity $\left({\lambda }_M\right)$ and equivalent conductivity $\left({\lambda }_{eq}\right)$ for an electrolyte $A_x{B}_y$ at any dilution are related as:

• A. ${\lambda }_M={\lambda }_{eq.}\times (x+y)$
• B. ${\lambda }_M={\lambda }_{eq.}\times x\times y$
• C. ${\lambda }_M=\frac{{\lambda }_{eq.}}{x+y}$
• D. ${\lambda }_M=\frac{{\lambda }_{eq.}}{x\times y}$

Answer 1

The correct option is B ${\lambda }_M={\lambda }_{eq.}\times x\times y$

Molar conductivity $\left({\lambda }_M\right)$ and equivalent conductivity $\left({\lambda }_{eq}\right)$ for an electrolyte $A_x{B}_y$ at any dilution are related as
${\lambda }_M={\lambda }_{eq.}\cdot x\cdot y$
${\lambda }_M={\lambda }_{eq.}\times$ total charge on cation or anion.
