What are double displacement reaction. Explain with example.

Explanation

The reaction in which a more reactive metal displaces a less reactive metal from its salt solution is called displacement reaction.
Example: Iron is more reactive than copper. So, it displaces copper from its salt solution.
`underset("(Grey)")(Fe) + underset("(Blue)")(CuSO_4) to underset("(green)")(FeSO_4) + underset("(Brown)")(Cu)`
