Coexistence curves in Electrical Conductivity of Critical Solution : Isobutyric Acid-Water with Added Ions
E. Cherif, und M. Bouanz. Abstract Book of the XXIII IUPAP International Conference on Statistical Physics, Genova, Italy, (9-13 July 2007)
Zusammenfassung
Results of comprehensive temperature $(T)$ studies of electrical conductivity
($\sigma$) in the one-and-two regions of the binary fluid mixture of
isobutyric acid-water with X MKCl at various critical concentrations are
presented. A strong asymmetry of determined coexistence curves causes a
strong violation of the law of rectilinear diameter.
The obtained critical anomalies in the homegeneous phase $\sigma_crit (T)$
or the diameter of the $\sigma_d (T)$ are associated with the same
critical exponent $= 1-0.88$, where $\alpha$ is
the specific heat critical exponent.
For the mixture with critical composition, the two regions show a
concentration behavior with $\sigma_l - \sigma_u |-t|^\beta$.
The phase-transition region shifts as a function of the salt concentration .
The effective-critical exponent $\beta^* = ( 0.264-0.296)$
is neither compatible with the Ising value $= 0.325$
nor with the Fisher renormalized value $0.365$.
