Question
Explain the following type of chemical reaction, giving two examples for it:
Displacement reaction
Advertisements
Solution
A displacement reaction occurs when a more active element displaces a less active element from a compound.
Examples:
- Zinc displaces copper from copper sulphate solution.
\[\ce{Zn + CuSO4_{(aq)} -> ZnSO4_{(aq)} + Cu}\] - Iron pieces when added to copper sulphate solution, copper is displaced.
\[\ce{Fe + CuSO4 → FeSO4 + Cu}\]

When a black metal compound XO is heated with a colourless gas Y2, then metal X and another compound Y2O are formed. Metal X is red-brown in colour which does not react with dilute acids at all. Gas Y2 can be prepared by the action of a dilute acid on any active metal. The compound Y2O is a liquid at room temperature which can turn anhydrous copper sulphate blue.
