Question

Derive the units of equivalent conductivity of a solution.

Derive the units of molar conductivities of an electrolytic solution and write expressions which show their mutual relationship.

Answer 1

We know that 

Λ_eq = κ × V_eq

= `(ohm^-1 cm^-1) xx ((cm^3)/(eq))`

= ohm⁻¹ cm² (eq)⁻¹

= ohm⁻¹ cm² eq⁻¹

Hence, the units of equivalent conductivity are ohm⁻¹ cm² eq⁻¹ or Ω⁻¹ cm² eq⁻¹ or S⁻¹ cm² eq⁻¹.
