2.31 deduce the position of a metal within the reactivity series using displacement reactions between metals and their oxides, and between metals and their salts in aqueous solutions

  • A more reactive metal will displace a less reactive material
  • Introduce a less reactive material and no reaction will take place

An example of a displacement reaction:

Zn (s) + CuSO4 (aq) –> ZnSO4 (aq) + Cu (s)

Reminder of the soluble metals (a more comprehensive list in spec point 4.6)

  • Cl- (chlorides) – All common chlorides are soluble in water, excluding silver chloride and lead chloride
  • NO3- (Nitrates) – All nitrates are soluble in water
  • SO4 2- (Sulfates) All common sulfates are soluble in water, excluding barium sulfate, Calcium sulfate and lead sulfate
