chemistry

• a displacement reaction is where a more reactive metal displaces a less reactive metal from a compound
• redox reactions involve the transfer of electrons, where one reaction is oxidised (loses electrons) and another is reduced (gains electrons)
• Using the principles of electron loss and gain it is possible to identify which species undergo oxidation and reduction in metal displacement reactions
• The more reactive metals displace the less reactive metals
• Oxidation


  The loss of electrons
• Reduction

  The gain of electrons
