In a displacement reaction, if a more reactive metal displaces a less reactive metal from its salt solution, what is the result?

Explanation

Official answer key: (4) Formation of an insoluble salt Correct answer should be (1). In a displacement reaction the more reactive metal displaces the less reactive metal from its salt solution and itself forms the compound (e.g. Fe + CuSO₄ → FeSO₄ + Cu). Forming an insoluble salt is not the result of a displacement reaction. Scoring follows the official key.
