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!
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.
