2.15, 2.17 Reactivity Series
Reactivity Series
Reactions to remember:
Metal + Water --> Metal hydroxide + hydrogen
Metal + hydrochloric acid --> metal chlride + hydrogen
Metal + sulphuric acid --> metal sulphate + hydrogen
Displacement Reactions
A more reactive metal is able to displace a less reactive metal from its solution
e.g. Magnesium + iron sulphate --> magnesium sulphate + iron
Mg + FeSO4 --> MgSO4 + Fe
Series
Potassium ** Really reactive metals are found in compounds
Sodium
Lithium
Magnesium
Aluminium
Carbon (for metal extraction)
Zinc
Iron
Tin
Lead
Hydrogen (tells us if a metal reacts with water)
Copper
Silver
Gold
Platinum
