Question

What is the effect of concentration in conductivity and molar conductivity?

Answer 1

Answer:

Conductivity changes with the concentration of the electrolyte. The number of ions per unit volume carrying the current decreases on dilution, so conductivity always decreases with decrease in concentration. However, molar conductivity increases with dilution.

Answer 2

$\huge\fbox\pink{♡Answer}$

Variation of molar conductivity with dilution

Variation of molar conductivity with dilutionFor weak electrolytes (i.e. incompletely dissociated electrolytes), however, the molar conductivity strongly depends on concentration: The more dilute a solution, the greater its molar conductivity, due to increased ionic dissociation.
