Question

What is displacement reaction??​

Answer 1

Answer:

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.

Answer 2

Explanation:

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.

A beaker contains copper sulfate solution, blue in colour and some magnesium powder. The beaker is stirred and the contents change to colourless magnesium sulfate solution and copper powder.

The atoms of the reactive magnesium give away electrons.

( = silvery metal atoms)

• ( = colourless soluble metal ions)

The ions of the less reactive copper are forced to accept these electrons.

( = blue ions)

( = brown metal powder)

The overall equation for the displacement of copper by magnesium is:
