The molar conductance of NaCl, HCl and CH3COONa at infinite dilution are 126.45, 426.16 and 91.0 Scm2 mol-1 respectively. The molar conductance of CH3COOH at infinite dilution is. Choose the right option for your answer.

  1. 201.28Scm2 mol-1
  2. 390.71 S cm2 mol-1
  3. 698.28Scm2 mol-1
  4. 540.48Scm2 mol-1

Solution

ΛmCH3COOH=ΛmCH3COONa+Λm(HCl)-Λm(NaCl)

=91+426.16-126.45

=390.71 S cm2 mol-1
