SI_unit_of_equivalent_conductance1556274980.jpg image

Equivalent conductance is defined as the conductance of an electrolyte solution containing one gram equivalent of the electrolyte. It is equal to the product of specific conductance (k) of the solution and the volume (V) of the solution that contains one gram equivalent of the electrolyte.

$λ$ = k x V

Unit of spceific conductance k is Siemens / m.

Volume of the solution V is $m^{3}$

Now, required equivalent conductance unit is $Siemens . m^{2} / equivalent$ .
