Question

Which of the following statements is correct for a strong electrolyte :

• A. ${\lambda }_m$ increases linearly with $C^{\frac{1}{2}}$
• B. ${\lambda }_m$ increases linearly with $C^2$
• C. ${\lambda }_m$ decreases linearly with $C^2$
• D. ${\lambda }_m$ decreases linearly with $C^{\frac{1}{2}}$

Answer 1

The correct option is D

${\lambda }_m$ decreases linearly with $C^{\frac{1}{2}}$

A plot of ${\lambda }_m{V}_S\sqrt{C}$ is linear with negative slope.
