Vapour pressure investigations of the systems here under discussion have frequently been carried out (cf. Olah, 1963). However, many of these studies are concerned with the question of the composition of the complexes formed in binary or ternary systems (Van Dyke, 1950 Brown and Pearsall, 1952 Brown and Brady, 1949, 1952 Brown and Wallace, 1953a, b Lieser and Pfluger, 1960a, b). To answer this question, the vapour pressm-e diagrams were recorded as a function of the composition of the binary or ternary system. The direct evaluation of the Henry s law constant, however, also permits the basicity of the unsaturated hydrocarbons to be determined. 

Fig. 2.4 The vapor pressure diagram of a dilute solution of the solute B in the solvent A. The region of ideal dilute solutions, where Raoult s and Henry s laws are obeyed by the solvent and solute, respectively, is indicated. Deviations from the ideal at higher concentrations of the solute are shown. (From Ref. 3.)...

The Danish astronomer Ejnar Hertzsprung and the American astronomer Henry Norris Russell independently observed a very well defined correlation between the luminosity and surface temperature of stars. That correlation is shown in Figure 12.7 and is called a Hertzsprung-Russell, or H-R, diagram. Most stars, such as our sun, fall in a narrow band on this diagram called the main sequence. Stars in this main sequence have luminosities L that are approximately proportional to 7 s5u3face, or in terms of their mass, M, L °c M3 5. How long a star stays on the main sequence will depend on its mass, which, in ton, is related to the reaction rates in its interior. 

Rousseau and Staton (1988) extended the y-x diagram plot to situations where a single component A is absorbed into the liquid and instantaneously reacts with a reactive species in the liquid. In this plot, the x axis is the fraction of reactive species in the liquid that has reacted with solute A, while the y axis is the ratio of moles of solute A in the gas to moles of solutefree gas. The equilibrium curve is derived using both Henry s Law constant and the reaction equilibrium constant. 

A similar derivation of the above relationship could have been achieved by proceeding via liquid expressions rather than the gas expressions used above. We are able to proceed via the latter, because at the Henry s Law end of the diagram ... 

Other two-dimensional methods for the representation of solubility data are the 5p-5h-diagram proposed by Henry (1974), the 5-5h-diagram proposed by Hoemschemeyer (1974) or the 5-5a-diagram.

When plotted on a log-probability scale (Henry s law diagram) the distributions of elemental concentrations show four patterns (Figure 1) (i) lognormal distribution as for potassium in Thailand (a, D), that can be interpreted as a single source of the element and limited control on its concentration (ii) retention...
