Abstract
Densities and viscosity of serine in 20, 40, and 60% (w/w) dimethy l sulfoxide
(DM SO)-water mixtures were measured at 298.15, 303.15 and 308.15k. From these
experimental data, apparent molal volume v
, limiting apparent molal volume v
o , the slop v S ,
transfer volume v
o(tr), Jones-Dole coefficients A and B were calculated. The results are
v
odiscussed the solute-solvent and solute-solute interaction, and showed that serine behaves
as structure-breaker in aqueous DMSO solvent.
