Cards (5)

  • redox reactions involve simultaneous oxidation and reduction reactions ( gain and loss of oxygen )
  • Oxidation
    • Gain of oxygen
    • loss of electrons
    • increase in oxidation number
  • Reduction:
    • Loss of oxygen
    • Gain of electrons
    • decrease in oxidation number
  • oxidising agent: substance that oxidises another substance and is itself reduced
  • reducing agent : substance that reduces another substance and is itself oxidised
