In physical chemistry, Henry's law is a gas law that states that the amount of dissolved gas in a liquid is directly proportional to its partial pressure above the liquid. The proportionality factor is called Henry's law constant. It was formulated by the English chemist William Henry, who studied the topic in … Meer weergeven In his 1803 publication about the quantity of gases absorbed by water, William Henry described the results of his experiments: … water takes up, of gas condensed by one, two, or … Meer weergeven When the temperature of a system changes, the Henry constant also changes. The temperature dependence of equilibrium constants can generally be described with the van 't Hoff equation, which also applies to Henry's law constants: Meer weergeven Values of Henry's law constants for aqueous solutions depend on the composition of the solution, i.e., on its ionic strength and on dissolved organics. In general, the solubility of a gas decreases with increasing salinity ("salting out"). … Meer weergeven Henry's law has been shown to apply to a wide range of solutes in the limit of infinite dilution (x → 0), including non-volatile substances such as sucrose. In these cases, it is necessary to state the law in terms of chemical potentials. For a solute in an ideal … Meer weergeven In production of carbonated beverages Under high pressure, solubility of CO 2 increases. On opening the bottle to atmospheric pressure, solubility decreases and the gas … Meer weergeven There are many ways to define the proportionality constant of Henry's law, which can be subdivided into two fundamental types: One possibility is to put the aqueous phase into the numerator and the gaseous phase into the denominator … Meer weergeven The Henry's law constants mentioned so far do not consider any chemical equilibria in the aqueous phase.
