1.	Which of the following is/are the reasons for more corrosiveness of industrial atmosphere than rural atmosphere?(a) Formation of sulfurous and sulfuric acid(b) Ejection of corrosive ammoniacal solutions(c) Formation of sulfurous and sulfuric acid and ejection of corrosive ammoniacal solutions(d) High levels of carbon dioxideThe question was posed to me in exam.The origin of the question is Environments topic in division Other Environments of Corrosion Engineering
Answer» The CORRECT option is (C) Formation of sulfurous and SULFURIC acid and ejection of corrosive ammoniacal solutions Easiest explanation: Formation of sulfurous and sulfuric acid from sulfur burning gases and ejection of corrosive ammoniacal solutions are the reasons of industrial corrosion. Whereas CARBON DIOXIDE is not corrosive in nature.
