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.
Here b = Experimental constant
Λ∞m = Molar conductivity at infinite solution.
The plot of Λ∞m versus would give a straight line.
The following curve is obtained when molar conductivity λm (y-axis) is plotted against the square root of concentration C1/2 (x-axis) for two electrolytes A and B.
(a) What can you about the nature of the two electrolytes A and B.
(b) How do you account for the increase in molar conductivity λm for the electrolytes A and B on dilution.
