What is the corresponding change in colour when iron nail is dipped in...
Explanation:
When an iron nail is dipped in a blue copper sulphate solution, a chemical reaction occurs between iron and copper sulphate. This reaction results in the displacement of copper ions by iron ions.
Colour Change:
The blue colour of the copper sulphate solution changes to a greenish color when the iron nail is dipped into it.
Reason for Colour Change:
The blue color of the copper sulphate solution is due to the presence of copper ions (Cu2+) in the solution. When the iron nail is dipped into the solution, iron ions (Fe2+) are formed by the displacement of copper ions. The greenish color is due to the formation of iron sulphate (FeSO4) in the solution.
Chemical Reaction:
The chemical reaction between iron and copper sulphate can be represented as follows:
Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s)
In this reaction, iron (Fe) displaces copper (Cu) from copper sulphate (CuSO4) to form iron sulphate (FeSO4) and copper metal (Cu).
Conclusion:
When an iron nail is dipped in a blue copper sulphate solution, the blue color of the solution changes to a greenish color due to the formation of iron sulphate. This change in color is an indication of the chemical reaction between iron and copper sulphate.
