An increase in equivalent conductance of a strong electrolyte with dilution is mainly due to
An increase in equivalent conductance of a strong electrolyte with dilution is mainly due to
increase in ionic mobility of ions
$100 \%$ ionisation of electrolyte at normal dilution
increase in both, ie, number of ions and ionic mobility of ions
increase in number of ions
Solution
$\lambda_{\text {eq }}=\kappa \times \mathrm{V}=\frac{\mathrm{k} \times 1000}{\text { normality }}$.
On dilution, the number of current carrying particles per $\mathrm{cm}^3$ decreases but the volume of solution increases. Consequently, the ionic mobility increases, which in turn increases the equivalent conductance of strong electrolyte.
