Question

Write the difference between Molar Conductance and Specific Conductance?

Answer 1

The molar conductance ($\Lambda$) is the conductance of 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. The unit of molar conductance is $S{m}^{2}mo{l}^{-1}$
Specific conductance ($\kappa$) is the conductance of unit cube of material.
The unit of specific conductance is $S{m}^{-1}$
The relationship between molar conductance and specific conductance is
$\Lambda =\frac{1000\kappa }{C}$
Here C is the molar concentration.
