Question

Air contains about 21% of oxygen by volume. When a sample ofriver water was boiled, the air expelled from the water was foundto conrain 30% of oxygen. What is the best explanation for thisdifference in oxygen content? (a)Carbon dioxide is more soluble in water than isoxygen (b)oxygen is more soluble in water then is nitrogen (c)Nitrogen reacts with water (d)the noble gases are insoluble in water Air contains about 21% of oxygen by volume.

(a)Carbon dioxide is more soluble in water than isoxygen (b)oxygen is more soluble in water then is nitrogen (c)Nitrogen reacts with water (d)the noble gases are insoluble in water

Explanation / Answer

This is because of the higher solubility of oxygen in water asoxygen can form hydrogen bonding with water. (b)oxygen is more soluble in water then isnitrogen Hope this helps!
