Displacement Reactions Learning Outcomes To be able to describe what happens during a displacement reaction. (Level 4) To be able to explain the process of a displacement reaction using a model. (Level 5) To be able to predict whether a chemical reaction will take place or not based on its reactivity. (Level 5-6) Key Words: Reactivity, displacement

increasing reactivity The reactivity series The reactivity series is the list of metals placed in order of their reactivity. The reactivity series can be used to make predictions about the reactions of metals. One way to remember this order is to learn this silly sentence: potassium sodium calcium magnesium aluminium zinc iron lead copper silver gold Please send Charlie’s monkeys and zebras in lead cages securely guarded! increasing reactivity

Displacement Zinc Copper Sulfate During a displacement reaction the metal in a compound is replaced with a more reactive metal to form a new compound. potassium sodium calcium magnesium aluminium zinc iron lead copper silver gold Zinc Copper Sulfate

A Model of a displacement Like people compounds find some partners more attractive than others, and will ‘ditch’ one metal for another.

Another Model In this model the non-metal part of the compound is like a footballer leaving his club for one higher up the league. CHELSEA ZINC COPPER SULFATE LIVERPOOL

Displacement of sulfates – predictions Use the reactivity series to predict if there is a reaction when these metals are added to different metal sulfate solutions. magnesium sulfate zinc sulfate iron copper sulfate magnesium copper metal sulfate solution metal              = displacement reaction = no reaction 

Displacement reactions – examples The reactivity series can be used to predict if a metal will react with a metal compound. Will magnesium react with copper chloride?  copper chloride + magnesium copper + magnesium chloride Magnesium is a more reactive metal than copper, so magnesium displaces the copper from its compound. Will silver react with magnesium chloride?  magnesium chloride + silver no reaction Silver is a less reactive metal than magnesium, so silver does not displace the magnesium from its compound.

Displacement of sulfates Does magnesium react with and displace these metal sulfates and if so what products are formed? Complete the word equations.  copper sulfate + magnesium magnesium sulfate + copper  zinc sulfate + magnesium magnesium sulfate + zinc  iron sulfate + magnesium magnesium sulfate + iron  magnesium sulfate + zinc no reaction  iron sulfate + zinc zinc sulfate + iron  zinc sulfate + copper no reaction
