Question

explain displacement reaction . give the chemical equation for recation of copper sulphate and iron .​​

Answer 1

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.

• Iron displaces copper ions from an aqueous solution of copper sulphate. It is a single displacement reaction of one metal by another metal. Iron is placed above copper in the activity series. Elements placed above in this series are more reactive than those placed below them.

Answer 2

• Displacement reactions are those reactions in which one element takes the place of another element in a compound.
• The more reactive element displaces the less reactive element from its compound.
• AB + C → AC + B.

Example: Zn + CuSO4 → ZnSO4 + Cu.

Iron displaces copper ions from an aqueous solution of copper sulphate. It is a single displacement reaction of one metal by another metal. Iron is placed above copper in the activity series. Elements placed above in this series are more reactive than those placed below them.
