Expected Changes
After placing a clean iron nail in a copper sulphate solution for about 10 hours, several changes can be expected:
- The nail will likely change color, showing signs of copper deposition.
- The blue color of the copper sulphate solution may fade over time.
Chemical Nature of Changes
The changes observed are indeed chemical in nature. This is due to the reaction between iron (Fe) and copper sulphate (CuSO₄). Iron is more reactive than copper, leading to the displacement of copper from the solution. The copper ions in the solution gain electrons and are reduced to metallic copper, which then deposits on the iron nail.
Word Equation for the Chemical Change
The word equation representing this chemical reaction can be written as follows:
Iron + Copper Sulphate → Copper + Iron Sulphate
Explanation of the Reaction
In this reaction:
- The iron (Fe) acts as the reducing agent, losing electrons to form iron ions (Fe²⁺).
- Copper ions (Cu²⁺) from the copper sulphate gain these electrons and are reduced to solid copper (Cu), which coats the iron nail.
- The leftover sulphate ions (SO₄²⁻) combine with the iron ions to form iron sulphate (FeSO₄), which remains dissolved in the solution.
This process is an example of a single displacement reaction, where one element displaces another in a compound, demonstrating the principles of reactivity in metals.
