Bronze and solder are two well-known alloys of tin. What are their respective co-metals?
ABronze = copper and tin; solder = tin and lead
BBronze = iron and tin; solder = tin and zinc
CBronze = tin and lead; solder = copper and tin
DBronze = tin and zinc; solder = copper and lead
Answer & Solution
Correct answer: A. Bronze = copper and tin; solder = tin and lead
1. Both bronze and solder are historically important tin alloys, each combining tin with a different second metal.
2. The text states: "Important tin alloys are bronze (Cu and Sn) and solder (Sn and Pb)."
3. Cu is copper and Pb is lead, so bronze pairs tin with copper while solder pairs tin with lead.
4. The other options swap these pairings or substitute unrelated metals (iron, zinc) that the text does not associate with either alloy.
5. So bronze is copper + tin, and solder is tin + lead.
