Question

Define molar and equivalent conductance of a solution .

Answer 1

Equivalent conductance is defined as the conductance of all the ions produced by one gram equivalent of an electrolyte in a given solution. Λ = κ.V, where V is the volume in mL containing 1 g equivalent of the electrolyte and k is specific conductance.

The molar conductance is defined as the conductance of all the ions produced by ionization of 1 g mole of an electrolyte when present in V mL of solution. It is denoted by .

Molar conductance   μ = k ×V  , where V is the volume in mL containing 1 g mole of the electrolyte. If c is the concentration of the solution in g mole per litre, then μ = k × 1000/c
