Answer :
Final Answer
Dew point corrosion occurs when the metal temperature is below the dew point. For sulfuric acid, this critical temperature is 310º F, making option C the correct choice.
Explanation
Dew point corrosion is a type of corrosion that occurs when the surface temperature of a metal is below the dew point temperature of the surrounding environment. In the case of sulfuric acid, its dew point is crucial to consider to prevent such corrosion. The correct answer is C. 310º F, as this temperature indicates the point at which sulfuric acid will start to condense on a metal surface, potentially leading to corrosion.
Dew point corrosion is a specific form of corrosion that arises from the interaction between a metal surface and a corrosive environment, particularly when the metal's temperature falls below the dew point of the surrounding atmosphere.
This phenomenon is of significant concern in industries where sulfuric acid is present, as it has a particularly corrosive effect on many metals. Understanding the dew point of sulfuric acid is essential for ensuring the integrity and longevity of metal structures and equipment in such environments. Engineers and professionals in industries dealing with sulfuric acid must be well-versed in this aspect to implement effective corrosion prevention measures.
