Q

A reddish-colored oxide usually forms on which of the following metals?

🔍 Key Concepts

• Common corrosion products of different shipbuilding metals • Typical color of iron oxide (rust) vs oxides of other metals • Where each listed metal is commonly used aboard ships

💭 Think About

• Think about which metal is the main ingredient in most ship hulls, anchors, and cargo gear and what color their corrosion product usually is. • Recall what color forms on aluminum surfaces when they oxidize—is it clear, white, dull gray, or reddish? • Consider which of these metals produces the classic "rust" you see on old piers, deck fittings, and anchor chains.

✅ Before You Answer

• Match the term "reddish-colored oxide" with the everyday word you normally use for that substance. • Eliminate any metals whose oxides are typically white, gray, or invisible rather than red-brown. • Think about which of these metals you most often see with flaking red-brown corrosion on ships and marine structures.
