🧠 Memory Aids
Acid + Base = Salt + Water: Remember "ABSW" — Acid plus Base gives Salt and Water. Easy to recall during an exam.
The four reaction types:
- Acid + Metal → Salt + H₂ (squeaky pop test)
- Acid + Metal Oxide → Salt + Water
- Acid + Metal Hydroxide → Salt + Water
- Acid + Metal Carbonate → Salt + Water + CO₂ (limewater test)
Salt naming rule: "Base gives the first name, Acid gives the surname." NaOH (sodium) + HCl (chloride) → sodium chloride. Ca(OH)₂ (calcium) + H₂SO₄ (sulfate) → calcium sulfate.
The ionic equation: H⁺ + OH⁻ → H₂O — just three symbols, always the same. Write it in the margin of your exam paper.
