Question

German silver contains:
A.\[Cu-Zn-Sn\]
B.\[Cu-Pb-Ni\]
C.\[Cu-Zn-Ni\]
D.\[Cu-Pb-Sn\]

Answer 1

Hint: German silver is an alloy. The alloy is defined as a substance which tends to form from the combination of two or more metals. It is a homogeneous mixture of two or more numbers of metals or a non metal and metal. This alloy was named as german silver because of its silver white colour

Complete step-by-step answer:
German silver also known as nickel silver is an alloy which has copper as its main component with the varying quantities of nickel and zinc and traces of tin and lead is also found in it. This ally is considered to be a tough, hard and also corrosion resistance. As its name has silver in it so the person thinks that it contains silver in it. But it has its name as german silver because of its colour of silvery white. The german silver has a varying quantity of components in it. These percentages of the components range a lot with copper having the highest percentage of all and zinc having the least percentage of all. As it has high electrical resistance so it is also used in heating coils. So it contains zinc, nickel and copper in it.

So, the correct answer is option (C).

Note:As it is tough, hard and corrosion resistance so it is used as tableware also in the fitting parts of ships. If the alloy of copper is in prolonged contact with the beverages and acidic foods it tends to leach out the copper thus causing toxicity. Many people have allergic reactions to nickel which causes rash.
