Electrochemistry
Kohlrausch examined L°m  values for a number of strong electrolytes
and observed certain regularities He noted that the difference in L°m  of
the electrolytes NaX and KX for any X is nearly constant For example
at 298 K:
L°
m (KCl) – L°
m (NaCl) = L°
m (KBr) – L°
m (NaBr)
= L°
m (KI) – L°
m (NaI) ≃ 23
