Oxygen solubility in seawater
WebOxygen solubility is negatively correlated with the amount of dissolved solids. Consequently, oxygen solubility in freshwater exceeds that in seawater by 1-3 mg/L, depending on temperature. The saturation constant in rivers and lakes in mountainous areas is usually lower than in lowlands, because it is pressure dependent. Web2 days ago · Seawater also contains various dissolved atmospheric gases, chiefly nitrogen, oxygen, argon, and carbon dioxide.
