The correct order of equivalent conductance at infinite dilution of LiCl, NaCl and KCl is

A

`LiCl gt NaCl gt KCI`

B

`KCI gt NaCl gt Lici`

C

`NaCl gt KCI gt LiCl`

D

`LiCl gt KCI gt NaCl`

Text Solution

Verified by Experts

The correct Answer is:
B
Extent of solvation decreases as `Li^+ > Na^+ > K^+` due to the effective size.
We know, ionic mobility `prop1/("effective size")`
Thus the equivalent conductance is in the order
KCI > NaCl > Lici

Conductors allow the passage of electric current through them. Metallic and electrolytic are the two type of conductors. Current carriers in metallic and electrolytic conductors are free electrons and free ions respectively. Specific conductance or consuctivity of the electrolyte solution is given by the following relation : kappa=c xx l/A where, c=1//R is the conductance and l//A is the cell constant. Molar conductance (Lambda_(m)) and equivalence conductance (Lambda_(e)) of an electrolyte solution are calculated using the following similar relations : Lambda_(m)= kappa xx 1000/M Lambda_(e)= kappa xx 1000/N Where, M and N are the molarity and normality of the solution respectively. Molar conductance of strong electrolyte depends on concentration : Lambda_(m)=Lambda_(m)^(@)-b sqrt(c) where, Lambda_(m)^(@)= molar conductance at infinite dilution c= concentration of the solution b= constant The degrees of dissociation of weak electrolytes are calculated as : alpha=Lambda_(m)/Lambda_(m)^(@)=Lambda_(e)/Lambda_(e)^(@) The correct order of equivalent conductances at infinite dilution of LiCl, NaCl and KCl is :
