Edexcel IAL Chemistry A2 14.1 Brønsted–Lowry acids and bases
Track a single H⁺ between species, identify the donor and acceptor from their formula change and write water as forming H₃O⁺ rather than free aqueous H⁺.
How this is tested
- Identify acidic donor hydrogens in carboxylic acid or phenol groups from a structure.
- Write HA + H₂O ⇌ H₃O⁺ + A⁻ to show aqueous Brønsted–Lowry acid behaviour.
- Classify each reacting species as proton donor or proton acceptor from the equation.
