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.
= 1.05 V – 0.0295 x log 80
= 1.05 V – 0.0295 x 1.9031
= 1.05 V – 0.056 = 0.99 V.
