📘
Theory
Compare displacement reactions between different metals and salt solutions in a matrix. To study displacement reactions and establish the reactivity series of metals using a matrix of metal-salt solution combinations.
∑
Formula
Principle: To study displacement reactions and establish the reactivity series of metals using a matrix of metal-salt solution combinations.
🎯
Aim
To study displacement reactions and establish the reactivity series of metals using a matrix of metal-salt solution combinations.
🧰
Apparatus
- Test tubes (12+)
- Metal strips: Zn, Fe, Cu, Pb
- Salt solutions: ZnSO₄, FeSO₄, CuSO₄, Pb(NO₃)₂
- Sandpaper
- Test tube stand
🧪
Procedure
- Clean all metal strips with sandpaper.
- Place each metal strip in each salt solution (4×4 matrix).
- Observe for colour change and deposition.
- A more reactive metal displaces a less reactive metal from its salt solution.
- Record results in a matrix table.
