Which condition is required for a displacement reaction between a metal and salt solution?
Metal must be higher in reactivity series
In a displacement reaction, a more reactive metal displaces a less reactive metal from the latter's salt solution.
Condition: The metal must be higher in the reactivity (activity) series than the metal in the salt solution.
Example: Zn + CuSO₄ → ZnSO₄ + Cu (Zinc displaces Copper because Zn is above Cu in the series).
If the displacing metal is lower in the series, no reaction occurs.
