Question

The order of equivalent conductance at infinite dilution of LiCl, NaCl and KCl
1) LiCl > NaCl > KCl
2) KCl > NaCl > LiCl
3) NaCl > KCl > LiCl
4) LiCl > KCl > NaCl

Answer 1

Answer:

option 2

Explanation:

In case of Alkali metals ions like sodium, lithium and potassium the hydration tendency follows the order,

Li+>Na+>K+

Hydration makes the cation heavier and larger 

Hence mobility has the following order : Li+<Na+<K+

Hence, the correct order of equivalent Conductance at infinite dilution of LiCl, NaCl and KCl is :

KCl>NaCl>LiCl
