📖 Key Definitions
Titre: The volume of solution added from the burette in a single titration run (final burette reading minus initial burette reading), measured in cm³.
Concordant results: Titration repeats that agree within 0.10 cm³ of each other. Only concordant results are averaged — anomalous results are discarded.
Endpoint (equivalence point): The precise point in a titration where the acid and alkali have completely neutralised each other. The indicator changes colour permanently at this point.
Indicator: A substance that changes colour depending on whether the solution is acidic or alkaline. Used in titrations to signal the endpoint.
Meniscus: The curved surface of a liquid in a tube. Always read the bottom of the meniscus in a burette, at eye level, to avoid parallax error.
