Question

What is displacement reaction?​

Answer 1

Answer:

Displacement reactions occur when a metal from the electrochemical series is mixed with the ions of a metal lower down in the electrochemical series. The atoms of the more reactive metal push their electrons on to ions of the less reactive metal.

Answer 2

$\large\sf\purple\maltese{\underline{\underline{Answer}}}$

Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound. Both metals and non-metals take part in displacement reactions.

Example : Reaction of iron nails with copper sulphate solution.
