|---|---|---|---|
| 1. | Soluble base + Acid (dil) | Salt + water | Neutralisation Titration |
| Eqn: HNO3 + NaOH ⟶ NaNO3 + H2O | |||
| 2. | Metal + Non-metal | Salt (soluble/insoluble) | Direct combination |
| Eqn: 2Fe + 3Cl2 ⟶ 2FeCl3 | |||
| 3. | Insoluble base + acid | Salt (soluble) + water | Neutralisation |
| Eqn: 2HCl + MgO ⟶ MgCl2 + H2O | |||
| 4. | Active metal + Acid (dil) | salt + hydrogen | Simple Displacement |
| Eqn: Fe + 2HCl ⟶ FeCl2 + H2 ↑ | |||
| 5. | Soluble salt solution (A) + Soluble salt solution (B) | Precipitated salt + soluble salt | Precipitation |
