Question

what is displacement reaction class 8

Answer 1

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.

A + B-C → A-C + B

The above equation exists when A is more reactive than B.

A and B have to be either:

Halogens where C indicates a cation.
Different metals wherein C indicates an anion.

Answer 2

Answer:

A more reactive metal displaces a less reactive metal from its salt solution. When a more reactive metal is placed in the salt solution of a less reactive metal,then the more reactive metal displaces the less reactive metal from its salt solution.
