Dühring's rule is a scientific rule developed by
Eugen Dühring which states that a linear relationship exists between the temperatures at which two solutions exert the same vapour pressure.
The rule is often used to compare a pure liquid and a
solution
Solution may refer to:
* Solution (chemistry), a mixture where one substance is dissolved in another
* Solution (equation), in mathematics
** Numerical solution, in numerical analysis, approximate solutions within specified error bounds
* Solu ...
at a given
concentration
In chemistry, concentration is the abundance of a constituent divided by the total volume of a mixture. Several types of mathematical description can be distinguished: '' mass concentration'', '' molar concentration'', '' number concentration'', ...
.
Dühring's plot is a
graphical representation of such a relationship, typically with the pure liquid's
boiling point
The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid and the liquid changes into a vapor.
The boiling point of a liquid varies depending upon the surrounding envi ...
along the x-axis and the mixture's boiling point along the y-axis; each line of the graph represents a constant concentration.
