Since l = 1 and A = V ( volume containing 1 mole of electrolyte)
Lm = k V
(2 22)
Molar conductivity increases with
decrease in concentration This is
because the total volume, V, of solution
containing one mole of electrolyte also
increases It has been found that decrease
in k on dilution of a solution is more
than compensated by increase in its
volume
