Ideal Solution

In chemistry, an ideal solution or ideal mixture is a solution with thermodynamic properties analogous to those of a mixture of ideal gases. The enthalpy of solution (or "enthalpy of mixing") is zero as is the volume change on mixing; the closer to zero the enthalpy of solution is, the more "ideal" the behavior of the solution becomes. The vapour pressure of the solution obeys Raoult's law, and the activity coefficients (which measure deviation from ideality) are equal to one.

The concept of an ideal solution is fundamental to chemical thermodynamics and its applications, such as the use of colligative properties.

Famous quotes containing the words ideal and/or solution:

    Most fatal, most hateful of all things is bullying.... Sensual bullying of course is fairly easily detected. What is more dangerous is ideal bullying. Bullying people into what is ideally good for them.
    —D.H. (David Herbert)

    Who shall forbid a wise skepticism, seeing that there is no practical question on which any thing more than an approximate solution can be had? Is not marriage an open question, when it is alleged, from the beginning of the world, that such as are in the institution wish to get out, and such as are out wish to get in?
    Ralph Waldo Emerson (1803–1882)
