Question 1
What is Kohlrausch's Law used for?
- To calculate total resistance
- To find molar conductivity at infinite dilution
- To determine boiling points
💡 Hint: Remember the focus of the law is on electrolytes and conduction.
Question 2
True or False: The degree of dissociation indicates how completely an electrolyte breaks down into ions in solution.
- True
- False
💡 Hint: Think about what happens when an electrolyte is added to water.

Challenge Problems
Push your limits with challenges.
Question 1
A weak electrolyte shows a molar conductivity of 12 S·m²/mol at a certain concentration and has a known Λ∞ of 60 S·m²/mol. What is the degree of dissociation?
💡 Hint: Use the degree of dissociation formula!
Question 2
If you have two electrolytes, A with λ+ = 30 S·m²/mol and λ- = 70 S·m²/mol, and B with λ+ = 50 S·m²/mol and λ- = 50 S·m²/mol. Which one has the higher total molar conductivity at infinite dilution?
💡 Hint: Add the contributions from each.
