🔍 Key Concepts

• Electrolytic (galvanic) corrosion between dissimilar metals in seawater • The purpose and common use of sacrificial anodes in marine systems • Which metals are typically used as sacrificial (more active) vs. which are protected

💭 Think About

• Think about what part inside a saltwater heat exchanger is meant to be slowly used up so the more expensive metal parts are not damaged. • Recall which metal in the answer choices is commonly attached to hulls, rudders, and cooling systems on boats to prevent corrosion. • Ask yourself: in a galvanic pair, does the more active (less noble) metal get protected, or does it get sacrificed to protect the other metal?

✅ Before You Answer

• Identify which listed metal is commonly used as a sacrificial anode on boats and marine engines. • Verify which metals from the choices are normally the ones you want to protect (tubes, housings) rather than sacrifice. • Make sure you are thinking about corrosion protection, not just structural parts or baffles inside the heat exchanger.
