Zinc Displaces Copper from Copper Sulphate Solution

Introduction:
When metallic zinc is added to a copper sulphate solution, a chemical reaction takes place. This reaction is an example of a displacement reaction, where a more reactive metal displaces a less reactive metal from its compound.

Explanation:
1. Displacement Reaction:
The reaction between metallic zinc and copper sulphate solution can be represented by the following equation:
Zn + CuSO4 → ZnSO4 + Cu
In this reaction, zinc (Zn) displaces copper (Cu) from the copper sulphate solution (CuSO4), resulting in the formation of zinc sulphate (ZnSO4) and solid copper (Cu).

2. Reactivity Series:
Metals can be arranged in a reactivity series based on their ability to displace other metals from their compounds. The reactivity series, from most reactive to least reactive, is as follows:
Potassium (K) > Sodium (Na) > Calcium (Ca) > Magnesium (Mg) > Aluminum (Al) > Zinc (Zn) > Iron (Fe) > Lead (Pb) > Copper (Cu) > Silver (Ag) > Gold (Au)
In this case, zinc is more reactive than copper, so it can displace copper from its compound.

3. Explanation of the Reaction:
When metallic zinc is added to a copper sulphate solution, the zinc atoms react with the copper sulphate. The zinc atoms lose electrons and are oxidized to form zinc ions (Zn2+). The copper ions (Cu2+) in the copper sulphate gain electrons and are reduced to solid copper. The zinc ions then combine with the sulphate ions (SO4) from the copper sulphate to form zinc sulphate, which remains in solution.

4. Visual Representation:
Zinc (Zn) + Copper Sulphate (CuSO4) → Zinc Sulphate (ZnSO4) + Copper (Cu)
- Zinc atoms lose electrons, become Zn2+
- Copper ions gain electrons, become solid copper
- Zinc ions combine with sulphate ions to form zinc sulphate

Conclusion:
In summary, when metallic zinc is added to a copper sulphate solution, zinc displaces copper from the solution. This displacement reaction occurs because zinc is more reactive than copper. The resulting reaction products are zinc sulphate in solution and solid copper.

Because copper is less reactive than Zinc. The High reactive aliment displaces the less reactive aliment. So the Zinc displaces copper from solution and Zinc sulphate(ZnSo4) is formed.
