Applications of Kohlrausch law
Using Kohlrausch law of independent migration of ions, it is possible to
calculate L
0
m  for any electrolyte from the lo of individual ions Moreover,
for weak electrolytes like acetic acid it is possible to determine the value
of its dissociation constant once we know the L
0
m  and Lm at a given
concentration c Calculate L
0
m  for CaCl2 and MgSO4 from the data given in Table 3 4
