Corrosion

Damage or destruction of metal objects over time

Noble metals

Metals that don't react with oxygen: Ag\text{Ag}, Pt\text{Pt}, Au\text{Au}

Metal + oxygen →

Metal oxide

Metal + water →

Metal hydroxide + hydrogen gas

Metal + steam →

Metal oxide + hydrogen gas

Metal + dilute acid →

Metal salt + hydrogen gas

Spectator ions

Ions that appear unchanged on both sides of equation

Displacement reaction

More reactive metal converts less reactive metal ions to atoms

Zn\text{Zn} in CuSO4\text{CuSO}_4 solution: observation

Zn covered with reddish-brown Cu; blue colour fades

When does displacement occur?

When metal is more reactive than metal ion in solution
