A more reactive metal can displace (remove) a less reactive metal from its compound
Competition Reactions
Similar to displacement reaction but none of the reactants are in a solution
In a competition reaction a fuse is needed to provide the energy for the reaction to start
Reduction
When a substance loses oxygen and gains electrons it has been reduced
Oxidation
When a substance gains oxygen and loses electrons it has been oxidised
Recycling Metals
Uses less energy than needed to extract metals from their ore
Less electricity needed - smaller greenhouse gas emissions
Less raw materials used - less waste in landfill sites
Inert
Unreactive electrodes used in electrolysis to prevent the electrode material affecting the reaction
Electroplating
The process of coating a metal with a thin layer of another metal by electrolysis to improve the metals corrosion resistance or to improve the metals appearance
