Ocean acidification Current Affairs, GK & News

Ocean Acidification

Ocean acidification refers to the ongoing consistent decrease in the pH of the Ocean water. When CO2 dissolved in the Ocean water, it creates Carbonic Acid (H2CO3) and increases the Hydrogen Ion (H+) concentration in the ocean. The Ocean acidification has fastened only after the Industrialization. Pre-Industrialization pH of the ocean water was 8.179. In ..
