Which gases are frequently found in water that encourage corrosion?

The presence of oxygen and carbon dioxide in water is significant in the context of corrosion. Oxygen is a key factor because it can react with metals, leading to oxidation, which is a fundamental process in rust formation. This oxidation can accelerate the degradation of metal pipes and structures, especially in environments that promote moisture.

Carbon dioxide contributes to corrosion through the formation of carbonic acid when it dissolves in water. This acid can lower the pH of the water, increasing its corrosivity toward metal materials. When combined, oxygen and carbon dioxide enhance the corrosive potential of water, often seen in natural water sources, which can significantly impact infrastructure, particularly in municipal water systems.

Understanding the roles of these gases helps in managing corrosion risks in water systems. Proper water treatment and corrosion control measures may be implemented when these gases are present in significant concentrations, thereby prolonging the lifespan of water delivery systems and protecting the integrity of structures that come into contact with water.
