Increased concentrations of co2 in the atmosphere leads to chemical changes in the ocean as well. the ocean absorbs about 30% of the co2 that is released in the atmosphere, and as levels of atmospheric co2 increase, so do the levels in the ocean. which of these does not accurately discuss chemical changes that occur in the process of ocean acidification?
a) when carbon dioxide (co2) is absorbed by seawater, chemical reactions occur that reduce carbonate ion concentration.
b) increases in co2 concentration and decreases in carbonate ion concentration affect the saturation states of biologically important calcium carbonate minerals.
c) increases in co2 concentration and increases in carbonate ion concentration, causes the release of excess h+, allowing for an increase in calcium carbonate minerals.
d) to achieve chemical equilibrium, some of the co2 reacts with the h20 to form carbonic acid. some of the resulting carbonic acid molecules dissociate into a bicarbonate ion and a hydrogen ion, thus increasing ocean acidity (h+ ion concentration).
