Textbook Question
Chapter 30.1, Problem 1MI
Figure 30.1 The Carbonate Equilibrium System. Atmospheric CO2 enters seawater and is converted to organic carbon (Corg) or to carbonic acid (H2CO3) that rapidly dissociates into the weak acids bicarbonate (HCO3−) and carbonate (CO32−). Calcium carbonate (CaCO3), a solid, precipitates to the seafloor, where it helps form a carbonate ooze. This system keeps seawater buffered at about pH 8.0.
Which carbon species, CO2 or CO32−, acidifies seawater?
