Answer:

This might not sound like much, but the pH scale is logarithmic, so this ... The ocean absorbs about 30% of the carbon dioxide (CO2) that is released in the atmosphere. As levels of atmospheric CO2 increase from human activity such as burning ... track and forecast ocean acidification, warming and other important ocean

An increase in atmospheric CO2 levels does not cause a decrease in the concentration of bicarbonate ions in the oceans.

WHAT IS OCEAN ACIDIFICATION?

  • Ocean acidification is the decrement in pH level of the ocean due to the absorption of carbon dioxide (CO2).

  • Carbon dioxide is a gas that reacts with water to form carbonic acid (H2CO3), which makes the water acidic or have a low pH.

CONSEQUENCE OF CO2 ABSORPTION IN OCEANS:

An increased CO2 level in the atmosphere means that the rate at which the ocean will absorb the atmospheric gas will it increase. Since CO2 is said to make the ocean acidic, the following will likely occur to increase acidity of the ocean:

  • Increase in the amount of carbonic acid (H2CO3) formed in the oceans
  • Decrease in the amount of calcium carbonate (CaCO3) produced in the oceans
  • Decrease in the concentration of carbonate ions (CO32-) in the oceans
  • Increase in the concentration of hydrogen ions (H+) in the oceans

N.B: Bicarbonate ion (HCO3-) causes acidity, hence, the decrease of bicarbonate ions cannot be a consequence of ocean acidification.
