State Kohlrausch’s law. Calculate the molar conductance of . The molar ionic conductance of and ions are and respectively.
Kohlrausch’s law states that Limiting molar conductivity of an electrolyte can be represented as the sum of the individual contributions of the anion and cation of the electrolyte.
Molar conductivity of Ba(OH)2 = λ0Ba+2 + 2 λ0OH- =127 + (2 x 199) = 525 Scm2 /mol
