SI unit of equivalent conductance

A) ohm/cm

B) Siemens m2/equivalent

C) Siemens/equivalent

D) mho/cm

Answer ::

Option B is correct.

Dear Student


Equivalent conductance is defined as the conducting power of all the ions produced by dissolving one gram equivalent of an electrolyte in solution.
It is expressed as
Λ = k•1000/M
Where k is the reciprocal of resistivity (1/ρ)
M is the molarity
The units are 1/(Ohm-Cm^2-(gm-equiv).
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.
The unit of specific conductance k is Siemens / m.
so,The required equivalent conductance unit is Siemens m^2/equivalent.
