Displacement reaction between magnesium and copper(II) sulfate. Diagram showing the colour change when magnesium displaces copper from copper(II) sulfate
Reactive magnesium displaces the less reactive copper from its compounds. Mg(s) + CuSO4(aq) → MgSO4(aq) + Cu(s) can also be written for this reaction. An ionic equation concentrates on the species that are reacting, and ignores the species that are no.
Magnesium may not produce as high a temperature change as zinc in the metal and acid reactions but it should be more reactive. This is because of the oxidised film on the outside of the Magnesium.
This worksheet provides information on the reactivity series of metals. The key points are: 1) Gold is unreactive and occurs naturally, while zinc is more reactive and oxidizes. Copper is used in wiring due to its conductivity and ductility.
28 lut 2020 · Both metals react with the hydrogen ions, but magnesium metal can also displace zinc ions in solution by the reaction: Mg (s) + Zn 2+ → Zn (s) + Mg 2+. This shows magnesium is more reactive than zinc and both metals are more reactive than hydrogen.
Displacement reactions of metals Reactions in solution Remember ribbon A metal will displace a less reactive metal from solutions of its compounds. For example, magnesium is more reactive than copper. When magnesium is put into copper(II) sulfate solution: • magnesium sulfate solution forms • copper coats the magnesium.
Demonstrate the ability of magnesium to remove oxygen from and oxide of copper with this practical, where students observe redox reactions. This demonstration activity should take about 20 minutes. The reaction is violent but safe, provided the procedure is followed exactly.
