Transcript of Reactivity of metals

Reactivity of metals
Aim
To know how to determine the reactivity of metals
To know how to RANK the reactivity of metals
Reaction of metals and water


A few very reactive metals will react with cold water. Potassium's reaction is the most violent that you are likely to encounter in the science lab.


Wth Oxygen
Metals such as potassium, sodium and lithium react with oxygen very quickly.
Calcium and magnesium are slightly less reactive and react with oxygen less quickly.
Metals like copper and mercury react with oxygen very slowly and need to be heated continuously in order to see this happening.
The product of burning a metal in oxygen is a metal oxide. For example -
2Mg + O2 → 2MgO

Reactivity of metals


More metals are able to react with acid than with water. Some very reactive metals like potassium are too dangerous to risk putting into acid, but metals such as:

Magnesium
Aluminium
Zinc
Iron
Tin can be added to acids
