Question

State Kohlrausch’s law of independent migration of ions.

Hint:

Kohlrausch’s law helps calculate:
- Limiting molar conductivity of weak electrolytes,
- Degree of dissociation,
- Ionic conductivities at infinite dilution.

Answer 1

Step 1: At infinite dilution, ions are far apart and do not interact with each other.
Step 2: Each ion migrates independently, contributing to the total molar conductivity.
Step 3: Hence, the total conductivity is additive, depending on the individual ion conductivities.
