Chapter 18, Problem 20TE

Some bottled water is now advertised as containing extra quantities of “Vitamin O,” which is a marketing gimmick for selling oxygen, ${\text{O}}_2$. Might this bottled water actually contain extra quantities of oxygen? How much more than one might find in regular bottled water? How might the amount of oxygen we absorb through our lungs compare to that we might absorb through our stomach – after burping?

To determine

This bottled water actually contain extra quantities of oxygen andthe actual amount more than one might find in regular bottled water andthe way the amount of oxygen we absorb through our lungs compare to that we might absorb through our stomach – after burping. When some bottled water is now advertised as containing extra quantities of “Vitamin O,” which is a marketing gimmick for selling oxygen, ${\text{O}}_2$.

Answer to Problem 20TE

Yes, bottled water contain extra quantities of oxygen. Very little more than one might find in regular bottled water. some amount of oxygen only is absorbed by the blood capillaries in the stomach from the digestion purpose

Explanation of Solution

The content of oxygen in bottled water can be increased by increasing the partial pressure of oxygen. But, oxygen has low solubility in water so, it will escape the solution as the extra pressure is removed or the bottle is opened.

A very small quantity of oxygen can only dissolve into water. Near 10 molecules of oxygen can get dissolved into one million water.

Out of the total gas content of the stomach, about 15-16% is oxygen. About 21% of oxygen is obtained through breathing. So, the bloodstream contains more oxygen than the stomach. Hence, some amount of oxygen only gets absorbed by the blood capillaries in the stomach from the digestion purpose.

Conclusion:

Therefore, bottled water contain extra quantities of oxygen. Very little more than one might find in regular bottled water.some amount of oxygen only is absorbed by the blood capillaries in the stomach from the digestion purpose
