Question

Give one example of displacement reaction . Stating the change in colour of the product formed

Answer 1

A displacement reaction is a type of reaction where part of one reactant is replaced by another reactant. A displacement reaction is also known as a replacement reaction or a metathesis reaction. There are two types of displacement reactions:

Single displacement reactions are reactions where one reactant replaces part of the other.

AB + C → AC + B

An example is the reaction between iron and copper sulfate to produce iron sulfate and copper:

Fe (grey)  + CuSO4 (blue) → FeSO4 (green) + Cu  (red-brown)

Here, both iron and copper have the same valence. One metal cation takes the place of the other bonding to the sulfate anion.
