How is molar conductivity related to concentration of an electrolyte? How will you explain a weak and a strong electrolyte based on their conductivity values?

Solution

conductivity and molar conductivity change with the concentration of the electrolyte. Conductivity always decreases with decrease in concentration both, for weak and strong electrolytes.

Molar conductivity varies with the concentration of electolytes.

$Λ_{m} = Λ_{m}^{\infty} - b \sqrt{C}$
Here b = Experimental constant
Λ∞_m = Molar conductivity at infinite solution.
The plot of Λ∞_m versus $\sqrt{C}$ would give a straight line.
