🧠 Memory Aids
Equipment placement: "BURETTE = BASE (usually), conical flask = ACID" — though either way round works, examiners most commonly set up the base in the flask and acid in the burette, or describe acid in the burette. The key is that the solution of unknown concentration goes in the flask, measured by pipette.
Indicator colours:
- Phenolphthalein: colourless in acid → PINK in alkali. Remember: "Phenol turns PINK in base."
- Methyl orange: RED in acid → yellow in alkali. Remember: "Methyl goes RED in acid."
- Litmus: red in acid, blue in alkali (not used in titrations — colour change is not sharp enough).
Titration calculation: "n = c × V, then RATIO, then c = n ÷ V" — three steps, always in that order.
