Question

A strip of a metal X is immersed in the aqueous solution of salt YSO4 blue in colour. After sometime, a layer of the metal Y from the salt solution is deposited on the strip of the metal X., whereas the metal X is used for galvanisation, the metal Y is employed in making electric cables. Can you name the salt YSO4? What is the nature of the chemical reaction taking place? Write all the applications, scope and utility of such type of chemical reactions in detail.​

Answer 1

Explanation:

a) Metal X is Zinc (Zn).

b) Metal Y is Copper (Cu).

c) The metal salt YSO4 is Copper sulphate

(CuSO4).

d) Displacement reaction takes place as X is more reactive than Y.

Reaction:

CuSO4 (aq)+Zn(s)→ZnSO4 (aq)+Cu(s)

e) Brass is the alloy made of Copper and Zinc.
