Kohlrauschlögmál
Kohlrausch's law, also known as the law of independent migration of ions, is an empirical law in physical chemistry that describes the molar conductivity of an electrolyte solution. It was discovered by Friedrich Kohlrausch in 1876.
The law states that at infinite dilution, the molar conductivity of a strong electrolyte is the sum
Mathematically, Kohlrausch's law can be expressed as:
Λ₀ = ν⁺λ⁺ + ν⁻λ⁻
where Λ₀ is the molar conductivity at infinite dilution, ν⁺ and ν⁻ are the stoichiometric coefficients of the cation
This law is particularly useful for determining the molar conductivity of weak electrolytes, which cannot be
Kohlrausch's law also provides evidence for the existence of ions in solution and supports the Arrhenius theory
