Molar conductivities (m) at infinite dilution of NaCl, HCl and CH3COONa are 126.4, 425.9 and 91.0 s cm2 mol-1 respectively.
m for CH3COOH will be :
180.5 S cm2 mol-1
290.8 S cm2 mol -1
390.5 S cm2 mol-1
425.5 S cm2 mol-1
As we discussed in
= 91+425.9+126.4
=
Option 1)
180.5 S cm2 mol-1
This option is incorrect.
Option 2)
290.8 S cm2 mol -1
This option is incorrect.
Option 3)
390.5 S cm2 mol-1
This option is correct.
Option 4)
425.5 S cm2 mol-1
This option is incorrect.
