[Color ﬁgure can be viewed in the online issue, which is available at wileyonlinelibrary.com.] Webreaches the boiling point of a second component in the mixture, and so on. The boiling point of a substance—determined by distillation—is a useful physical property for the characterization of pure compounds. At any given temperature a liquid is in equilibrium with its vapor. This equilibrium is described by the vapor pressure of the liquid. cs2334 cityuWebThese mixtures have a boiling point greater than their respective constituents. They are also known as negative azeotropes or pressure minimum azeotropes. An example is hydrochloric acid at a concentration of 20.2% and 7.8% water (by mass), with a boiling point of 110℃. HCl has a boiling point of -84℃ and water has a boiling point of 100℃. cs233 lab github
