what is a displacement reaction
A displacement reaction is one in which an element or group is displaced from a chemical compound by another element or group. In single displacement reactions, the more reactive element displaces the less reactive one.ingle displacement reactions include the replacement of a metal in a salt with a more reactive metal. For example, iron will displace copper from a copper sulfate solution because it is more reactive: Fe+ CuSO 4 4. This type of reaction can be used for metal plating. 2 + H2.
