Laws Henry’s Law

Henry s Law applies to the vapor pressure of the solute in dilute solutions, and is a modification of Raoult s Law Henry s Law—... 

The ideal solution law, Henry s Law, also enters into the establishment of performance of ideal and non-ideal solutions. 

Another expression for the total standard partial molar Gibbs free energy is obtained from Henry s law. Henry s law may be written... 

Both Eqs. (24) and (26) are different versions of Henry s Law. Henry s Law is valid for predicting air-water equilibria for many organic pollutants of concern. Henry s law is valid in the following range ... 

Henry s Law. Henry s Law expresses the effect of pressure on the solubility of a gas in a liquid. It may be stated The weight of gas dissolved in a given quantity of liquid and at a given temperature is directly proportional to the pressure of the gas. 

Henry s law The decreased solubility of the carbon dioxide contained in the beverage after its cap is removed can be described by Henry s law. Henry s law states that at a given temperature, the solubility (S) of a gas in a liquid is directly proportional to the pressure (P) of the gas above the liquid. You can express this relationship in the following way... 

Unfortunately, relatively few mixtures follow Raoult s law. Henry s law is a more empirical relationship used for representing data on many systems. Here,... 

In gas absorption operations the equilibrium of interest is that between a relatively nonvolatile absorbing liquid (solvent) and a solute gas (usually the pollutant). As described earlier, the solute is ordinarily removed from a relatively large amount of a carrier gas that does not dissolve in the absorbing liquid. Temperature, pressure, and the concentration of solute in one phase are independently variable. The equilibrium relationship of importance is a plot (or data) of x, the mole fraction of solute in the liquid, against y, the mole fraction in the vapor in equilibrium with x. For cases that follow Henry s law, Henry s law constant m, can be defined by the equation... 

As witli Raoult s law, Henry s law is only an approximation. However, we can generalize its range of validity by defining an activity coefficient y as... 

Like Raonii s Law. Henry s Law is of limited use for accurate work. However, realistic versions of Eq. (1.3-17) suitable, for example, for gas-solubilily calculations, are easily developed. If we adopt approximation [ and also aseume that T" is indepandent of pressure, then Eqs, (1.5-17) and (1.5-23) yield... 

An important issue that has haunted the practitioners of experimental trace element partitioning is that of Henry s law. Henry s law is said to be obeyed if the partition coefficient does not depend upon the concentration of the tracer. There has been some question as to whether trace elements doped at the wL% level, for the purposes of electron microprobe analysis, are truly in the Henry s law region [49, 103]. The main challenge to percent-level doping came from beta track studies, which have sub-sequratly been disputed, as noted above. It is the opinion of... 

Like Raoult s law, Henry s law applies within a concentration range whose extent varies from one system to another, but it is valid only at low concen-. tration.
