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
