Study Notes
Reactivity Series of Metals
- Metals can be arranged in order of reactivity based on reactions with water, acids, and oxygen.
- More reactive metals react more vigorously, forming metal hydroxides or oxides and hydrogen gas.
- Non-metals, like hydrogen and carbon, are also included in the reactivity series as they are used to extract metals.
Reactions of Metals with Water
- Most reactive metals (Potassium, Sodium, and Calcium) react with cold water, forming metal hydroxides and hydrogen gas.
- Less reactive metals (Magnesium and Aluminium) react with steam, forming metal oxides and hydrogen gas.
- The least reactive metals (Copper, Silver, and Gold) do not react with cold water or steam.
Reactions of Metals with Acids
- Metals above hydrogen in the reactivity series react with dilute acids, forming a salt and hydrogen gas.
- Less reactive metals (Gold, Silver, and Copper) do not react with acids.
- The more reactive the metal, the faster the reaction with the acid.
Reaction with Oxygen
- Reactive metals (Alkali metals) react easily with oxygen, forming metal oxides.
- Less reactive metals (Silver, Copper, and Iron) react with oxygen but much more slowly.
- Gold does not react with oxygen.
Deducing Order of Reactivity
- Order of reactivity can be deduced by observing reactions with water, acids, and oxygen.
- More vigorous reactions indicate higher reactivity.
- Temperature changes in reactions can also indicate reactivity: larger temperature changes mean higher reactivity.
Displacement Reactions
- A more reactive metal can displace a less reactive metal from a solution of its salt.
- More reactive metals are better reducing agents and lose electrons more easily.
- Less reactive metals are better electron acceptors and are reduced.
- Magnesium displaces copper from copper sulfate solution, forming magnesium sulfate and copper metal.
Reactivity of Aluminium
- Aluminium is highly reactive but appears less reactive due to a protective layer of aluminium oxide.
- This layer prevents reaction with water and dilute acids.
How to Determine the Reactivity of a Metal
- To determine the reactivity of a metal, observe the reactions with water, acids, and oxygen.
- The more vigorous the reaction, the higher the metal's position in the reactivity series.
