III. German silver : Cu, Zn, Cr
Choose the correct answer.
In which of the following sets, the alloy is correctly matched with its components?
I. Brass : Cu, Zn
II. Bronze : Cu, Sn
III. German silver : Cu, Zn, Cr
Choose the correct answer.
Show Hint
Remember: Brass = Cu + Zn, Bronze = Cu + Sn, German Silver = Cu + Zn + Ni.

Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Check Statement I
Brass is an alloy of:
Copper (Cu) and Zinc (Zn)
So,
\[
\boxed{\text{Statement I is correct}}
\]
Step 2: Check Statement II Bronze is an alloy of: Copper (Cu) and Tin (Sn) So, \[ \boxed{\text{Statement II is correct}} \]
Step 3: Check Statement III German silver is actually an alloy of: Copper (Cu), Zinc (Zn), and Nickel (Ni) It does not contain Chromium (Cr). So, \[ \boxed{\text{Statement III is incorrect}} \] Correct statements are: \[ I,\ II \] \[ \boxed{\text{I, II only}} \] Therefore, the correct answer is: \[ \boxed{(D)} \]
Step 2: Check Statement II Bronze is an alloy of: Copper (Cu) and Tin (Sn) So, \[ \boxed{\text{Statement II is correct}} \]
Step 3: Check Statement III German silver is actually an alloy of: Copper (Cu), Zinc (Zn), and Nickel (Ni) It does not contain Chromium (Cr). So, \[ \boxed{\text{Statement III is incorrect}} \] Correct statements are: \[ I,\ II \] \[ \boxed{\text{I, II only}} \] Therefore, the correct answer is: \[ \boxed{(D)} \]
