🔍 Key Concepts

• Boiler water chemistry and how it prevents corrosion • Difference between chemicals that cause corrosion vs. chemicals added to control or prevent corrosion • Role of dissolved gases (like oxygen) in attacking metal surfaces

💭 Think About

• Look at each choice and ask: is this pair of substances normally present in a boiler as a contaminant that attacks metal, or as a treatment chemical added by engineers? • Think about what happens when untreated feedwater enters a boiler and is heated: which substances naturally present in water (and from its breakdown) would attack steel from the inside? • For the options that include treatment chemicals, what are those chemicals usually used for in boiler water programs?

✅ Before You Answer

• Identify which listed substances are commonly used as oxygen scavengers or corrosion inhibitors (these are usually not the main cause of corrosion). • Recall that dissolved gases in feedwater are a major concern in boiler design and operation. • Make sure you distinguish between corrosion products and conditioning or treatment chemicals added intentionally.
