9. Solutions

Hyperbaric chambers, which provide high pressures (up to 6 atm) of either air or pure oxygen, are used to treat a variety of conditions, ranging from decompression sickness in deep-sea divers to carbon monoxide poisoning. Look up the solubility of O₂, N₂, CO, and CO₂ in water at standard temperature and pressure (1 atm, 25 °C).Explain the trends in relative solubility for these gases. (Refer to Section 8.2 and Section 9.2)

Look up the solubility of O₂, N₂, CO, and CO₂ in water at standard temperature and pressure (1 atm, 25 °C).Explain how elevated pressures in a hyperbaric chamber be used to treat decompression sickness (excess N₂ in blood) and carbon monoxide poisoning.
