Q. An increase in equivalent conductance of a strong electrolyte with dilution is mainly due to

AIPMTAIPMT 2010Electrochemistry

Solution:

$\lambda_{\text {eq }}=\kappa \times V=\frac{k \times 1000}{\text { Normality }}$
On dilution, the number of current carrying particles per $cm ^{3}$ decreases but the volume of solution increases.
Consequently, the ionic mobility increases, which in turn increases the equivalent conductance of strong electrolyte.
