For years, scientists have considered it a possible solution for increasing the alkalinity of seawater, and conversely, lowering the growing acidity level. When CO 2 dissolves in seawater, it produces carbonic acid as a byproduct. When you add lime to seawater, it reacts with that acid and neutralizes it, forming a carbonate ion.
