📌 Key Facts: Naming Salts
The name of a salt comes from TWO parts:
- First part: from the metal or base (e.g., sodium, copper, calcium)
- Second part: from the acid used:
- Hydrochloric acid (HCl) → chloride
- Sulfuric acid (H₂SO₄) → sulfate
- Nitric acid (HNO₃) → nitrate
Examples:
- NaOH + HCl → Sodium chloride (NaCl)
- Ca(OH)₂ + H₂SO₄ → Calcium sulfate (CaSO₄)
- KOH + HNO₃ → Potassium nitrate (KNO₃)
Quick Check: Name the salt formed when potassium hydroxide reacts with nitric acid.
Potassium nitrate (KNO₃). The metal comes from the base (potassium hydroxide → potassium), and the ending comes from the acid (nitric acid → nitrate). Equation: KOH + HNO₃ → KNO₃ + H₂O.
Practice questions for Neutralisation Reactions
Which word equation correctly represents a neutralisation reaction?
Explain why the ionic equation for any strong acid-alkali neutralisation is always H⁺(aq) + OH⁻(aq) → H₂O(l).
