  • Electrolysis
    • When ionic substances are dissolved in water or molten, the ions are free to move within it
    • Passing electric currents through molten/dissolved substances breaks them down into elements
    • The substance that's broken down is called the electrolyte
    • Positively charged ions move to the negative electrode, and negatively charged ions move to the positive electrode.
    • Objects can be electroplated using electrolysis
      • E.g. copper plating and silver plating
    • At the negative electrode, positively charged ions gain electrons (reduction), and positively charged ions lose electrons (Oxidisation)
      • OILRIG
    • If there's a mixture of ions, the products formed depend on the reactivity of the elements involved
