CRITICAL OPALESCENCE
December
1910.
In
1911
Wolfgang
Ostwald
compared
earlier
experimental
results obtained
by
Jacob Friedländer
(Friedländer
1901)
on
the
opalescence
of mixtures of
liquids
with the
Smoluchowski-Einstein
theory, obtaining,
at
a
certain distance from the critical
point,
a
rather
satisfactory agreement
for the
temperature dependence
of
the
absorption
due to critical
opales-
cence;
see
Ostwald
1911.
