Abstract
Isentropic compressibilities of solutions
κS are readily calculated using the
Newton–Laplace equation together with measured speeds of sound and
densities. The result is an apparent molar isentropic compression for a
given solute-j, ϕ(KSj; def) and a
limiting property, ϕ(KSj;
def)∞. This review examines the definition and calculation
of ϕ(KSj; def) and
ϕ(KSj; def)∞, commenting
on the related isentropic expansions,
ϕ(ESj; def) and
ϕ(ESj; def)∞. We
describe the thermodynamics which underpins the use of isentropic
properties in the study of solute–
