🔍 Key Concepts

• Galvanic corrosion between dissimilar metals in seawater • Role of sacrificial anodes (zincs) in a cooling system • Difference between corrosion protection and fouling/marine growth control

💭 Think About

• Ask yourself: What is the main job of a zinc anode when it’s installed in contact with seawater and metals? • Which choice talks about stopping or reducing metal loss due to electrical/chemical action in seawater, rather than cleaning or coating? • Which options are really about cleanliness or marine growth, and which are about protecting metal from being eaten away?

✅ Before You Answer

• Verify which option refers to electrical/chemical attack on metals in seawater rather than physical cleanliness • Eliminate any choices that focus mainly on shiny/clean surfaces or marine growth, since that is not the primary purpose of zincs • Check that the remaining choice correctly matches the function of a sacrificial anode: it is the metal that is meant to be consumed first
