Corrosiveness of steam condensate is due to the presence of________________?
Correct answer: C. Both A. & B.
- A. CO2
- B. Dissolved O2
- C. Both A. & B.
- D. Neither A. nor B.
Explanation
Carbon dioxide dissolves in condensate to form carbonic acid, while dissolved oxygen promotes oxidation and pitting. Both gases therefore contribute to the corrosiveness of steam condensate.
