The acidity of oceans is greatly influenced by carbon dioxide (CO2). Human activities like burning fossil fuels and deforestation release CO2 into the atmosphere, a significant portion of which is absorbed by the oceans. This absorption, known as ocean acidification, causes an increase in hydrogen ions in the water, leading to lower pH levels and higher acidity.
When CO2 dissolves in seawater, it combines with water molecules to create carbonic acid (H2CO3). This chemical reaction releases hydrogen ions (H+), which elevate the water's acidity. The increased acidity disrupts the delicate chemical balance necessary for life in the ocean, especially reactions involving calcium carbonate.
Calcium carbonate plays a vital role in the formation of shells and skeletons for various marine organisms, such as corals, shellfish, and certain plankton. As ocean acidity rises, it becomes more challenging for these creatures to construct and maintain their calcium carbonate structures. This can result in stunted growth, weakened shells, and heightened susceptibility to predators and diseases.
Ocean acidification also has implications for the entire marine food chain. Many species depend on shell-forming organisms as a food source or as habitats, and their decline can have a ripple effect on the entire ecosystem. Additionally, acidification can disrupt the balance of phytoplankton, which are microscopic plants crucial for marine food chains.
Furthermore, carbon dioxide in the ocean can interact with water to generate bicarbonate ions (HCO3-) and carbonate ions (CO32-). These ions are crucial for maintaining proper pH levels and enabling marine organisms to regulate their internal chemistry. However, as CO2 levels increase, the concentration of carbonate ions decreases, making it more challenging for organisms to obtain the carbonate they need to build their shells and skeletons.
Overall, the impact of carbon on ocean acidity is significant and has far-reaching consequences for marine life. It is essential to reduce carbon emissions and implement measures to mitigate and adapt to the effects of ocean acidification in order to safeguard the health and biodiversity of our oceans.
Carbon dioxide (CO2) is a major contributor to the acidity of oceans. When CO2 is released into the atmosphere through human activities such as burning fossil fuels and deforestation, a significant portion of it is absorbed by the oceans. This process, known as ocean acidification, leads to an increase in the concentration of hydrogen ions in the water, resulting in a decrease in pH levels and an increase in acidity.
When CO2 dissolves in seawater, it reacts with water molecules to form carbonic acid (H2CO3). This reaction releases hydrogen ions (H+), which increase the acidity of the water. The increased acidity affects the delicate balance of chemical reactions that support life in the ocean, particularly those involving calcium carbonate.
Calcium carbonate is a vital component in the formation of shells and skeletons of many marine organisms, including corals, shellfish, and some plankton. As the acidity of the ocean increases, it becomes harder for these organisms to build and maintain their calcium carbonate structures. This can lead to reduced growth rates, weakened shells, and increased vulnerability to predators and disease.
Ocean acidification also affects the entire marine food web. Many species rely on shell-forming organisms as a food source or as habitat, and their decline can have cascading effects on the entire ecosystem. Additionally, acidification can disrupt the balance of phytoplankton, the microscopic plants that are the foundation of marine food chains.

Carbon dioxide (CO2) dissolves in seawater to form carbonic acid (H2CO3), which increases the concentration of hydrogen ions (H+) in the water, leading to ocean acidification. This decrease in pH affects marine life by hindering the ability of shell-forming organisms to build and maintain their shells, as well as impacting other vital biological processes.
