🔍 Key Concepts

• How dissolved oxygen in water reacts with steel/iron surfaces inside a boiler • The difference between general corrosion, pitting, and embrittlement • Typical causes of caustic embrittlement versus oxygen-related damage in boilers

💭 Think About

• Think about how oxygen in water attacks metal: does it usually cause wide, uniform wear or very small, concentrated damage areas? • Which option is most closely associated with oxygen forming rust (iron oxide) on steel surfaces inside the boiler? • Which of the listed problems is more commonly linked to chemical imbalance or high alkalinity, rather than to oxygen itself?

✅ Before You Answer

• Match dissolved oxygen specifically with the type of metal damage it is most famous for in boiler feedwater systems. • Eliminate any choices that are more related to alkaline (caustic) conditions instead of oxygen presence. • Ask yourself which problem operators try to prevent by adding oxygen scavengers (like sodium sulfite) to boiler feedwater.
