Question

How does molar conductivity vary with increase in concentration for strong

electrolyte and weak electrolyte? How can you obtain limiting molar conductivity
(∧m
0
) for weak electrolyte?
​

Answer 1

Answer:

There is sharp increase in the number of ions in the solution. Hence, the molar conductivity of a weak electrolyte rises steeply at low concentration. (ii) Strong electrolytes: The molar conductivity of a strong electrolyte decreases slightly with the increase in concentration.

Answer 2

Answer:

On increasing dilution molar conductivity of strong electrolyte and weak electrolyte increases therefore on increasing concentration molar conductivity will decrease.

Limiting Molar conductivity

Limiting Molar conductivity =

$\frac{conductivity}{molarity} \times 1000$

unit of molar conductivity

$s \: {cm }^{2} {mol}^{ - 1}$
