Statement I: The limiting molar conductivity of KCl (strong electrolyte) is higher compared to that of (weak electrolyte).

Statement II: Molar conductivity decreases

Question

Given below are two statements:

Statement I: The limiting molar conductivity of KCl (strong electrolyte) is higher compared to that of  (weak electrolyte).

Statement II: Molar conductivity decreases with decrease in concentration of electrolyte.

In the light of the above statements, choose the most appropriate answer from the options given below:

Canvas Classes · Accepted Answer

Strategy:
 Evaluate the statements using Kohlrausch's law and the general laws of electrolytic conductance.

Statement I:
The limiting molar conductivity () for  (\approx 391) is actually significantly higher than that of  (\approx 150) mainly due to the 	extremely high mobility of  ions. So, Statement I is False.

Statement II:
Molar conductivity increases as concentration decreases (dilution). The statement says it "decreases", which is incorrect. So, Statement II is False.

Conclusion:
Both
