Ideal solution

An ideal solution in physics is a homogeneous mixture of 2 or more components, the creation of which is not accompanied by the release or absorption of heat, nor with the change in volume.

The entropy of the mixture is calculated in the same way as for the mixture of ideal gases .

The ideal solution fulfills Raoult's laws (with - partial vapor pressure of a component of the solution, - the corresponding vapor pressure of the pure component, - its molar fraction) and Henry (with - Henry's constant) in the full concentration range; with it . ${\displaystyle P=P^{o}x}$ ${\displaystyle P}$ ${\displaystyle P^{o}}$ ${\displaystyle x}$ ${\displaystyle P=Kx}$ ${\displaystyle K}$ ${\displaystyle K=P^{o}}$
