Low henry's law constant
WebThe Henry’s constant typically increases with tempera- ture at low temperatures, reaches a maximum, and then decreases at higher temperatures. The temperature at which the maximum occurs depends on the specific solute-solvent pair. WebHenry's law refers to small concentrations (lim c→0). Maximum solubilities are not included. Solubility products, i.e. products of ion concentrations are not included either. Henry's …
