Even though the air we breathe contains mostly n2, this gas has no known effect on bodily functions, and at sea level pressure very little of it dissolves in blood plasma because its solu(cid:271)ilit(cid:455) is (cid:448)er(cid:455) lo(cid:449).

You have probably noticed that a soft drink makes a hissing sound when the top of the container is removed, and bubbles rise to the surface for some time afterward. The gas dissolved in carbonated beverages is co2. Because the soft drink is bottled or canned under high pressure and capped, the co2 remains dissolved as long as the container is unopened. Once you remove the cap, the pressure decreases and the gas begins to bubble out of solutio(cid:374).
