Question

The correct order of equivalent conductance at infinite dilution of LiCl, NaCl and KCl is (a) LiCl > NaCl > KCl (b) KCl > NaCl > LiCl(c) NaCl > KCl > LiCl (d) LiCl > KCl > NaCl

Answer 1

Hi there,

Answer: KCl > NaCl > LiCl

# Reason

We know that the Hydration energy of Molecule decreases with increase in the atomic number of the Alkali Metals. LiCl has hydration energy Greater than other compounds. As you know, Mobility increases with a decrease in Hydration energy. At last Higher the Mobility, Higher will be the Equivalent Conductance. So, the order of Equivalent Conductance is KCl > NaCl > LiCl.

Hope it helped.
