State Kohlrausch's law and write mathematical expression of molar conductivity of the given solution at infinite dilution. |
|
Answer» Solution :Statement of Kohlrausch's LAW : This states that at infinite dilution of the solution, each ion of an electrolyte migrates indepef!dently of its co-IONS and contributes independently to the total molar conductivity of the electrolyte, irrespective of the nature of other ions present in the solution This law of independent MIGRATION of ions is represented as `^^_(0) = lambda_(+)^(0) + lambda_(-)^(0)`. Where `^^_(0)`is the molar conductivity of the electrolyte at infinite dilution or ZERO concentration while `lambda_(+)^(0)`and `lambda_(-)^(0)`arethe molarionicconductivites of cationand anionrespectively atinfintedilution. |
