Question

German silver is used for making beautiful cutlery, jewellery or tea sets. It is made of $60\%$ copper along with:
A.Chromium and lead
B Cobalt and iron
C.Nickel and zinc
D.Silver and lithium

Answer 1

The materials made up from the combination of two or more metals are known as alloys. They retain the properties of their parent metals and evolve some new properties like toughness and high strength. German silver is also an alloy.

Complete step by step answer:
Cutlery are the equipment used in preparing, serving and eating of food items, basically it is a part of western culture. It is made up of German silver.
When two or more metals are combined with each other then a new substance is formed and this substance is called as an alloy. Alloy can also be formed from the combination of metals with other elements.
The resulting material alloy differs in properties from its core elements or parent elements. The alloy formed has new and better properties than the pure metal. The strength and hardness increases but the properties which a metal has are retained in an alloy, the properties like electrical conductivity, ductility and luster are transferred from metal to the alloy.
German silver is also an alloy. It is formed from the combination of copper, zinc and nickel. The composition of elements in the German silver alloy is : $60\%$ copper, $20\%$ nickel and $20\%$ zinc.
This alloy is named after its colour, it has silver white colour that is why it is called as German silver but now the term ‘silver’ can’t be used in the names if the alloy doesn’t contain that element.

So, the correct answer is Option C .

Note:
As we all know that alloys are made up from the combination of elements and one of these elements is a metal which is known as base metal, the naming of alloy is done on the basis of that base metal. Example: Aluminium alloy.
