Question

German silver is an alloy of -

• A. $\mathrm{Fe},\mathrm{Cr},\mathrm{Ni}$
• B. $\mathrm{Ag},\mathrm{Cu},\mathrm{Au}$
• C. $\mathrm{Cu},\mathrm{Zn},\mathrm{Ni}$
• D. $\mathrm{Cu},\mathrm{Zn},\mathrm{Sn}$

Answer 1

The correct option is C

$\mathrm{Cu},\mathrm{Zn},\mathrm{Ni}$

Explanations for the correct option:

Option (C): $\mathrm{Cu},\mathrm{Zn},\mathrm{Ni}$

1. An alloy is a substance formed from the combination of two or more metals.
2. Alloys can also be formed from combinations of metals and other elements. In simpler words, an alloy can be defined as a homogeneous mixture of two or more metals or a metal and a nonmetal.
3. German silver is a term for various Copper, Zinc, and Nickel alloys, often even containing Lead and Tin.
4. German silver is also known as Nickel silver and has the main component Copper with varying quantities of Nickel and Zinc
5. German silver is widely used because of its hardness, toughness, and resistance to corrosion.
6. Hence, it is the correct answer.

Therefore, German silver is an alloy of$\mathrm{Cu},\mathrm{Zn},\mathrm{Ni}$.
