Reactivity Series

Most Reactive ↓
K > Na > Li > Ca > Mg > Al > Zn > Fe > Ni > Sn > Pb > H > Cu > Hg > Ag > Pt > Au
↑ Least Reactive

Metals higher in the series displace metals lower from their salt solutions.

Displacement Reactions

Metal + CuSO₄ + FeSO₄
Zn ✓ Reacts ✓ Reacts
Fe ✓ Reacts ✗ No reaction
Cu ✗ No reaction ✗ No reaction
Did you know? Gold (Au) is so unreactive that ancient gold artifacts remain shiny after thousands of years!

🎯 Aim

To study the relative reactivity of Zn, Fe, Cu, and Al by observing displacement reactions and arrange them in decreasing order.

Theory

A displacement reaction occurs when a more reactive metal displaces a less reactive metal from its salt solution.

A + BC → AC + B
(If A is more reactive than B)
  • Blue CuSO₄ → Green FeSO₄ (with Fe)
  • Blue CuSO₄ → Clear ZnSO₄ (with Zn)
  • Green FeSO₄ → Clear ZnSO₄ (with Zn)
