WebHenry's law dictates that when temperature is constant, the solubility of the gas corresponds to it's partial pressure. Consider the following formula of Henry's law: p = kh c. where: p is the partial pressure of the gas above the liquid, kh is Henry's law constant, and. c is the concentrate of the gas in the liquid.
