"Nettet9. des. 2015 · Ocean acidification itself is a fairly simple chemical process. As carbon dioxide (CO 2) dissolves in water (H 2 O), it creates carbonic acid (H 2 CO 3 ), which is a weak acid. Carbonic acid dissociates into hydrogen ions (H +) and bicarbonate ions (HCO 3-1 ), and the hydrogen ions bond with carbonate ions (CO 3-2) in the water. In the … " - How ocean acidification happens
