An element 'X' displaces iron from the aqueous solution of iron sulphate. List your observations if the element 'X' is treated with the aqueous solutions of copper sulphate, zinc sulphate and silver nitrate. Based on the observations arrange X, Zn, Cu and Ag in increasing order of their reactivities.

Observations with different salt solutions

  1. CuSO? (blue) + X → reaction occurs

    • Observation: Reddish-brown copper metal deposits on X blue colour fades (solution becomes pale/colourless) as Cu²? is displaced.

  2. ZnSO? (colourless) + X → no reaction (since Zn is more reactive than most metals above Fe)

    • Observation: No change in solution; no deposit on X.

  3. AgNO? (colourless) + X → reaction occurs

    • Observation: Grey/silvery deposit of Ag on X; solution remains colourless (forms XNO?).

Reactivity order (increasing): Ag < Cu < X< Zn

X can displace Cu and Ag. So X is more reactive than both but cannot displace Zn, X is less reactive than Zn.
