Short Note

In the plot of molar conductivity (∧m) vs square root of concentration (c1/2), following curves are obtained for two electrolytes A and B:

Answer the following:
(i) Predict the nature of electrolytes A and B.
(ii) What happens on extrapolation of ∧m to concentration approaching zero for electrolytes A and B?

Solution

(i) 
A =  Strong electrolyte   
B =  Weak electrolyte

(ii) On extrapolation of these graphs they cut the Y-axis it means concentration is approaching zero and at that point, we will say infinite dilution of their respective A and B.       
When A and B cut on Y-axis then we will say molar conductivity of A and B at infinite dilution.
