Which one of the following statements is NOT correct for the given reaction? Fe ( s )+ CuSO ₄( aq ) FeSO ₄( aq )+ Cu ( s )
Options
- AIron is the reducing agent
- BThe solution turns green in colour after the reaction
- CCopper is a more reactive metal than iron
- DThe reaction is an example of a redox reaction
Correct answer
C. Copper is a more reactive metal than iron
Step-by-step solution
Copper is not more reactive than iron. Cu ⁺ FeSO ₄- Cu ⁺ FeSO ₄ As you can see, copper does not displace iron from its solution since it is less reactive than iron. A more reactive metal displaces a less reactive metal from its solution.
