This memory aid covers Memory Aids within Titrations (HT) for GCSE Chemistry. Revise Titrations (HT) in Quantitative Chemistry for GCSE Chemistry with 22 exam-style questions and 20 flashcards. This topic shows up very often in GCSE exams, so students should be able to explain it clearly, not just recognise the term. It is section 11 of 14 in this topic. Use it for quick recall, then test yourself straight afterwards so the memory aid becomes usable in an answer.

🧠 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.
