There are a number of ways that you could investigate a displacement reaction. This is an outline of the required steps to undertake one of these methods.
Some students did not test combinations of the same metal, such as magnesium and magnesium sulfate solution. Suggest why.
A metal cannot displace itself, so no reaction would take place.
Which metal is the most reactive?
Magnesium is the most reactive metal because a displacement reaction takes place with all the salt solutions.
It is important in this practical activity to use appropriate apparatus and methods. This includes the safe use and careful handling of substances.
Evaluate the hazards and the precautions needed to reduce the risk of harm. For example:
|Salt solutions||Irritate the eyes||Wear eye protection|
|Salt solutions||Metal ions absorbed through the skin||Carefully wipe up spills and wash hands|
