Rusting is an oxidation reaction. Each … A more reactive metal donates electrons more readily to form a cation. This provides the driving force for metal displacement reaction. Memorise the reactivity series of metals without memorising. The unreactive metals do not react at all, even when we use strong acid or high temperature. This happens because iron is more reactive than copper. A more reactive metal will displace a less reactive metal from solution. It is used to determine the products of single displacement reactions, whereby metal A will replace another metal B in a solution if A is higher in the series. This means they do not easily take part in chemical reactions. Reactivity Series of Metals. We say that iron has displaced copper from copper(II) oxide. When we drop iron into copper sulfate solution, a dramatic precipitation of reddish-brown copper occurs. Firstly, reactivity affects what a metal can react with.
