A strip of metal X is dipped in a blue coloured salt solution YSO4. 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.
(a) What could metal X be?
(b) What could metal Y be?
(c) Name the metal salt YSO4
(d) What type of chemical reaction takes place when metal X reacts with salt solution YSO4? Write the equation of the chemical reaction involved.
Name the alloy Z.

Question

A strip of metal X is dipped in a blue coloured salt solution YSO4. 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.
(a)	What could metal X be?
(b)	What could metal Y be?
(c)	Name the metal salt YSO4
(d)	What type of chemical reaction takes place when metal X reacts with salt solution YSO4? Write the equation of the chemical reaction involved.
Name the alloy Z.

Metal X is Zinc (Zn)
Metal Y is Copper (Cu)
Copper sulphate (CuSO4) is named as YSO4
Displacement reaction;Displacement reaction is a reaction in which one active element displaces a less reactive element from its salt solution

CuSO4 (aq) + Zn (s) &rarr; ZnSO4 (aq) + Cu (s)
