The molar conductivities of KCl, NaCl and KNO3 are 152, 128 and 111 S cm2 mol-1 repectively. What is the molar conductivity of NaNO3 ?
101 S cm2 mol-1
87 S cm2 mol-1
-101 S cm2 mol-1
-391 S cm2 mol-1
As we have learnt,
Formula for limiting molar conductivity for electrolyte -
are limiting molar conductivities of cation and anion respectively.
- wherein
if an electrolyte on dissociation gives anions.
Option 1)
