applications of reactivity series of metals

Reactivity series the arrangement of metals in decreasing order of their reactivity.

It helps in concluding the result of displacement reactions between a metal and the salt solution of other metal.

The more reactive metal can displace a less reactive metal from its salt solution but a less reactive metal can not displace a more reactive metal from its salt solution.

For example: 

Fe can replace Cu from CuSO4 solution to form FeSO4.

But there is no reaction between the Cu and FeSO4 solution.

This is simply because Fe is more reactive than Cu.

This arrangement aids the understanding of the properties of metals, helps to explain differences between them.

enables predictions to be made about a metal's behaviour, based on a knowledge of its position or properties.

It also allows prediction of the relative stability of the compounds formed by an element: the more reactive the metal, the more stable its compounds are likely to be.

The position of a metal in the series determines the reactions of the metal with various reagents, the displacement of one metal from its compound by another metal, and the method of extraction of a metal from its ore.

the metal will react with chemicals in the human body.some metals react more strongly with oxygen or water. We learn there is a 'league table' of chemical reactivity called a reactive series. Potassium and sodium are at the top, being the most reactive metals, and silver and gold are at the bottom, being the least reactive.

One of its application is in extacting metals of lower reactivity by high reactive metals
