Define "Molar conductivity".
Define molar conductivity for the solution of an electrolyte.
उत्तर १
Molar conductivity is the conductance of a volume of solution containing 1 mole of dissolved electrolyte when placed between two parallel electrodes 1 cm apart and large enough to contain between them all the solution.
उत्तर २
The conductivity, which is shown by all the ions when 1 mol of electrolyte is dissolved in the solution, is called molar conductivity; it is expressed by ∧m (lambda). If 1 mol of electrolyte is present in V cm3 of electrolyte solution, then ∧m = κ × V
= `(κ xx 1000)/"Molarity" = (κ xx 1000)/"M"`
Its unit is ohm−1 cm2 mol−1 or S cm2 mol−1.
