Reactivity Series and Metal Extraction

• Order of Reactivity

  Please Stop Calling Me A Careless Zebra Instead Try Learning How Copper Saved Gold
• Reactivity Series

  -The reactivity of a metal is related to how easily it forms positive ions.

  -Chemical reactions can be used to place metals in order of reactivity.
• Metal Extraction

  -Unreactive metals are found as elements

  -Electrolysis:Only use if carbon is less reactive than the metal

  -Reduction with carbon:(displacement reaction)

  -Only use if carbon is more reactive than the metal and if carbon won't react with the metal
• What is being oxidised and what is being reduced?

  Mg+2HCL-->MgCI2+H2


  Mg oxidised-Start charge is 0,End charge is 2+ so it loses 2 to become 2+

  H reduced-Start charge is 1+,End charge is 0 so it gains 1 to become 0
• OILRIG


  Oxidation is Loss of Electrons(Loses to become charged) whilst Reduction is Gain of Electrons(Gains to become charged)
