"Web29 dec. 2024 · Henry's law provides a basis to determine the solubility of gases in liquids. Henry found that at a constant temperature, the concentration of a soluble or semi-soluble gas in a liquid was proportional to the partial pressure of the gas that is in equilibrium with the liquid. The proportionality constant is known as the Henry's law constant (HLC). " - Henry's law constant for hydrogen

Refer to Figure 14.1 and notice the hydrogen atoms bear a partial positive charge. Thus, the hydrogen atoms in a water molecule are attracted to the negative iodide ion. WebIts partitioning between gas and aqueous phases in the atmosphere, usually described by its Henry's law constant (K (H)), significantly influences its role in atmospheric processes. Large discrepancies between the K (H) values reported in previous work, however, have created uncertainty for atmospheric modelers.
