  • Metal-acid reactions are redox reactions
  • Redox means reduction and oxidation at the same time
  • If we analyse the ionic equation for the reaction between zinc and hydrochloric acid:
    Zn + 2HCl ⟶ ZnCl2 + H2
  • The ionic equation is:
    Zn + 2H+⟶ Zn2+ + H2
  • This equation can be further split into two half equations illustrating oxidation and reduction individually:
    Zn → Zn2+ + 2e
    2H+ + 2e→ H
    2
  • The zinc atoms are thus oxidised as they lose electrons.
  • The hydrogen ions are thus reduced as they gain electrons.
  • Both reactions are occurring at the same time and in the same reaction chamber hence it is a redox reaction

Exam Tip

Remember metal atoms tend to lose electrons and in these reactions are usually the species that undergoes oxidation.
