kohlrausch's law

Question

According to Kohlrausch's law, the molar conductivity at infinite dilution for a salt can be calculated from:

RankGuru · Accepted Answer

**Kohlrausch's Law of Independent Migration of Ions** states that at infinite dilution, where dissociation is complete, each ion makes a definite contribution to the total molar conductivity, regardless of the nature of the other ion.
- Formula: $\Lambda^\circ_m = 
u_+ \lambda^\circ_+ + 
u_- \lambda^\circ_-$
- $\lambda^\circ_+, \lambda^\circ_-$ are limiting molar conductivities of cations and anions.
- $
u_+, 
u_-$ are the number of cations and anions produced by one formula unit of the salt.
- Therefore, the total molar conductivity is the **sum** of the individual ionic conductivities.
