When a zinc rod is kept in a copper nitrate solution what happens?a)zi...
Explanation:
Introduction:
When a zinc rod is kept in a copper nitrate solution, a redox reaction occurs between zinc and copper ions present in the solution.
Redox Reaction:
- Zinc metal (Zn) is more reactive than copper (Cu), so it displaces copper ions in the solution.
- The zinc rod undergoes oxidation, losing electrons to form zinc ions (Zn2+).
- Copper ions (Cu2+) in the solution gain electrons from the zinc rod and get reduced to copper metal (Cu).
- This reaction results in the deposition of copper metal on the zinc rod.
Chemical Equation:
Zn(s) + Cu(NO3)2(aq) -> Zn(NO3)2(aq) + Cu(s)
Result:
- As a result of the redox reaction, a layer of copper metal is deposited on the surface of the zinc rod.
- The color of the solution may change from blue (copper nitrate solution) to colorless (zinc nitrate solution).
- The zinc rod may appear to be coated with a layer of copper metal.
Conclusion:
In conclusion, when a zinc rod is kept in a copper nitrate solution, copper metal is deposited on the zinc rod due to a redox reaction between zinc and copper ions.
