5.2: Distribution and Solubility of Gases in Seawater

  • Page ID
  • ---Still needs information about distribution of gases in the ocean---

    The solubility of gases in seawater is a temperature dependent relationship, solubility is highest in cold water, and lowest in warm water. Henry's Law explains the relationship between the partial pressure of a gas and the solubility of the gas in water in this equation:

    \[[C] = k P_{gas} \]


    • \([C]\) is the solubility of the gas
    • \(k\) is Henry's Law Constant
    • \(P_{gas}\) is the partial pressure of the gas
