What do you understand by a displacement reaction ? give one example
Answers
Answer:
A displacement reaction is the one wherein the atom or a set of atoms is displaced by another atom in a molecule. For instance, when iron is added to a copper sulphate solution, it displaces the copper metal.Some other examples of displacement reactions which can occur are: zinc displacing iron ions from iron(II) sulfate solution. nickel displacing copper from copper(II) nitrate solution. copper displacing silver from silver(I) nitrate solution.
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.
An example can be seen below
Cu(s) + 2AgNo3(aq) → 2Ag(s) + Cu(NO3)2(aq)
This is your answer
