"Soldering becomes easy due to the addition of flux". Why?

Explanation

### Step-by-Step Solution:

1. **Understanding Soldering**: Soldering is a process used to join two or more electronic components together by melting solder around the connection. The solder typically contains a mixture of metals.

2. **Role of Oxidation**: When metals are exposed to air, they can oxidize, forming a layer of oxide on their surface. This oxide layer can prevent proper adhesion of the solder to the metal surfaces, making soldering difficult.

3. **Introduction of Flux**: Flux is a chemical cleaning agent that is applied to the surfaces to be soldered. It helps in cleaning the metal surfaces by removing any oxide layers that may have formed.
