  • The cell constant of a conductivity cell is given by

  • A conductivity cell has two platinum electrodes of area 1.2 cm21.2 \ cm^2 and 0.92 cm apart. Hence the cell constant is

  • The conductivity of 0.02 M KI solution is 4.37×104Ω1cm1.4.37 \times 10 ^{-4} \Omega ^{-1} \, cm ^{-1}. Hence its molar conductivity is :

  • The specific conductance of 0.02 M HCl is 8.2×103Ω1cm1.8.2 \times 10 ^{-3} \, \Omega ^{-1}\, cm ^{-1}. Hence its molar conductivity is :

  • Molar conductivity of an electrolyte is given by,

  • The units of molar conductivity are

  • If conductivity is expressed in Ω1 m1\Omega^{-1} \ m^{-1} and concentration of the electrolytic solution in mol m3m^{-3} then, the molar conductance is given by

  • Kohlrausch’s law is represented as

  • The degree of dissociation of a weak electrolyte is given by

  • 0\wedge_0 for CH3COOHCH_3 COOH is 390.7 Ω1 cm2 mol1390.7 \ \Omega^{-1} \ cm^2 \ mol^{-1} . If 0\wedge_0 for CH3COOKCH_3 COOK, and HBr in Ω1 cm2 mol1\Omega^{-1} \ cm^2 \ mol^{-1} are 115 and 430.4 respectively, then 0\wedge_0 for KBr is
