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

  • the increase in ionic mobility of ions

  • 100% ionisation of electrolyte at normal dilution

  • the increase in both, ie, the number of ions and ionic mobility of ions

  • the increase in the number of ions

Solution

A.

the increase in ionic mobility of ions

straight lambda subscript eq space equals space straight k space straight x space straight V space equals space fraction numerator straight k space straight x space 1000 over denominator normality end fraction
on dilution, the number of current carrying particles per cm3 decreases but the volume of solution increases. Consequently, the ionic solution increases. Consequently, the ionic mobility increases, which in turn increases the equivalent conductance of strong electrolyte.
