A strip of metal X is dipped in a blue-salt solution ${YSO}_{4}$ . After some time, a layer of metal Y from the salt solution is formed on the surface of metal strip X. Metal X is used in galvanisation whereas metal Y is used in making electric wires. Metal X and metal Y together form an alloy Z. Is it true that the alloy Z is brass?

Detailed Solution

The above statement is true.
An alloy is a homogeneous compound made up of two elements. An alloy is a combination (or solid solution) of two or more metals or one or more metals and a nonmetal solution. Alloys are typically created by melting two metals together. Metal X is zinc, and metal Y is copper. The alloy of zinc and metal is called brass. Brass is commonly used in applications that require low friction due to its unique properties, which include corrosion resistance. Fittings (fasteners and connectors), tools, appliance parts, and ammunition components are examples of such applications.
