Why is the amount of carbon dioxide dissolved in seawater much less than the theoretical maximum
saturation level?
a. Carbon dioxide is very soluble in water.
b. Carbon dioxide is able to form a weak acid when combined with seawater.
c. Carbon dioxide is quickly used by photosynthetic organisms.
d. Carbon dioxide moves quickly from the atmosphere to the ocean
ANS: C
Carbon dioxide chemically combines with water quite quickly which creates carbonic acid, but the low
level in comparison to the theoretical maximum saturation level is due to photosynthetic organisms
using it quickly. Information can be found in the section Gases Dissolve in Seawater.
