USING THE REACTIVITY SERIES AND DISPLACEMENT
REACTIONS
1.Dicplacement reactions in industry
2.Displacement using carbon
i
In order for the thermite reaction to take
place, the iron oxide and aluminium
mixture has to be ignited. This is done using
another exothermic reaction – this time
between magnesium powder and barium
nitrate. This reaction provides the energy to
start the displacement reaction between
the aluminium and iron oxide.
