The molar conductivity of CH 3 COOH at infinite dilution is 390 Scm 2 /mol. Using the graph and given information, the molar conductivity of CH 3 COOK will be:

Question 5 - The molar conductivity of CH3COOH - teachoo.jpg

  1. 100 Scm 2 /mol
  2. 115 Scm 2 /mol
  3. 150 Scm 2 /mol
  4. 125 Scm 2 /mol

 

Answer:

b. 115 Scm 2 /mol

Λ O CH 3 COOK = Λ O CH 3 COOH +Λ O KCl - Λ O HCl = 390 +150-425 = 115 Scm 2 /mol
