(HIGH OXIDATION POTENTIAL)
K (Potassions) → Most Reactive Na (Sodium) (Low Reduction Potential) Mg (Magneium) Al (Aluminium) Zn (Zinc) Cu (Copper) Ag (Silver) Au (Gold) (High Reduction Potential) Pt (Platinum) → Least Reactive (Low Oxidation Potential)
- Mg + CuSO4 → MgSO4 + Cu
Ag + NaCl → Can’t displace the salt
“More reactive metal displaces less reactive metal from it’s salt”
- Mg → Mg2+ + 2e {Oxid. Po = E1, Red Po = E3}
Zn → Zn2+ + 2e {Oxid. Po = E2, Red Po = E4}
Zn + MgSO4 → X
Mg + ZnSO4 → NgSO4 + Zn
⇒ E1 > E2
E3 < E4
- X x → x+ + e- E1 {Oxidation Potential}
Y y → y+ + e- E2 {Oxidation Potential}
if E1 > E2 then X is more reactive than Y
