Question

When lead powder is added to copper chloride solution, a displacement reaction
occurs and solid copper is formed.
i) Write the equation for the reaction.
ii) Why does the displacement reaction occur?

Answer 1

Pb+CuCl2--PbCl2+Cu.......here Displacement reaction occurs because lead powder reacts with chlorine gas removing solid copper.....

Answer 2

Pb+CuCl2=PbCl2+Cu

This reaction implies that lead when reacted with copper chloride results in the formation of lead chloride and copper.

This is an example of redox-reaction or reduction and oxidation reaction.

At the same time this reaction is an example of single displacement reaction.

The copper atom in copper chloride is displaced by the lead atom and this results in the formation of lead chloride and copper.
