Consequences

Solvent-Solute interactions are agnate to solute-solute and solvent-solvent interactions

Since the enthalpy of bond (solution) is zero, the change in Gibbs chargeless activity on bond is bent alone by the anarchy of mixing. Hence the molar Gibbs chargeless activity of bond is

ΔGm,mix = RT ∑ xiln xi

i

or for a two basic solution

ΔGm,mix = RT(xAln xA + xBln xB)

where m denotes molar i.e. change in Gibbs chargeless activity per birthmark of solution, and xi is the birthmark atom of basic i.

Note that this chargeless activity of bond is consistently abrogating (since anniversary xi is absolute and anniversary ln xi have to be negative) i.e. ideal solutions are consistently absolutely miscible.

The blueprint aloft can be bidding in agreement of actinic potentials of the alone components

ΔGm,mix = ∑ xiΔμi,mix

i

where Δμi,mix = RTln xi is the change in actinic abeyant of i on mixing.

If the actinic abeyant of authentic aqueous i is denoted \mu_i^*, again the actinic abeyant of i in an ideal band-aid is

\mu_i = \mu_i^* + \Delta \mu_{i,\mathrm{mix}} = \mu_i^* + RT \ln x_i

Any basic i of an ideal band-aid obeys Raoult's Law over the absolute agreement range:

\ P_{i}=(P_{i})_{pure} x_i

where

(P_i)_{pure}\, is the calm breath burden of the authentic component

x_i\, is the birthmark atom of the basic in solution

It can aswell be apparent that volumes are carefully accretion for ideal solutions.
