🔍 Key Concepts

• Boiler water treatment purpose in marine steam systems • Effects of dissolved gases (like oxygen and carbon dioxide) on boiler metal surfaces • Which chemicals are used specifically as oxygen scavengers

💭 Think About

• Ask yourself: which dissolved substance is most directly responsible for internal corrosion and pitting of boiler steel, and needs a chemical "scavenger"? • Think about typical boiler water treatment chemicals: which one is used for oxygen removal, and which are used for pH control or scale prevention? • Match sodium sulfite’s role: is it mainly targeting corrosion from oxygen, acidity from CO₂, or something else?

✅ Before You Answer

• Identify which choice names a dissolved gas commonly present in untreated feedwater that causes corrosion. • Recall that sodium sulfite is commonly listed in engineering texts as an oxygen scavenger – confirm what that means. • Eliminate any options that are not naturally present in raw feedwater in significant amounts.
