Question:
Identify metals present in brass.
Identify metals present in brass.
Show Hint
Brass is an alloy of copper and zinc.
Updated On: Oct 1, 2026
- Ni and Cu
- Fe and Zn
- Cr and Sn
- Cu and Zn
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
An alloy is a mixture of a metal with other elements. Common alloys are tested often in the d-block chapter.
Step 2: Composition of Brass:
Brass is about 60-80% copper and 20-40% zinc.
Step 3: Compare the Options:
Ni and Cu: this pairing is found in the alloy called cupronickel (coins).
Fe and Zn: not a standard alloy pair.
Cr and Sn: not a standard alloy pair either.
Cu and Zn: brass.
Step 4: Conclusion:
The metals in brass are copper and zinc, option (D).
Final Answer:
Brass contains Cu and Zn, option (D). \[ \boxed{\text{(D) Cu and Zn}} \]
