When CO$_2$ from the atmosphere dissolves in seawater, it reacts to form carbonic acid (H$_2$CO$_3$). Carbonic acid then dissociates, releasing hydrogen ions (H+) and bicarbonate ions (HCO$_3^-$). The increase in hydrogen ions lowers the pH of the seawater, making it more acidic.
Ozone Layer it more acidic. Increased CO₂ in the atmosphere due to factors causing global warming leads to increased CO₂ uptake by the ocean, driving this acidification process. 308. What is the primary cause of ocean acidification?
