Question

Change in colour when lead added to cupric chloride

Answer 1

It will become brown in colour and displacement reaction

Answer 2

Answer: Green color changes to red brown coating of copper.

Explanation:

$Pb+CuCl_2\rightarrow Cu+PbCl_2$

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.Thus lead can easily lose electrons as compared to copper and result in the formation of lead chloride and copper.

The green color of lead fades and forms colorless solution of lead chloride and red brown coating of copper deposits.
