The volume delivered from a burette during a titration, calculated as the final burette reading minus the initial reading.
Used by AQA, Edexcel and OCR
Specification 4.4.2.5 · Paper 1
The volume delivered from the burette during a titration, found by subtracting its initial reading from its final reading.
Revise: TitrationsSubtract the initial reading from the final reading to obtain the titre, the volume delivered. Repeat carefully until titres agree closely, then find their mean without including the rough trial.
Specification 3.18, 5.9C, 5.10C · Paper 1
The volume of solution delivered from a burette, calculated by subtracting its initial reading from its final reading.
Revise: Acid-Alkali Titration MethodThe volume of acid delivered, or titre, is the final reading minus the initial reading.
The volume delivered from a burette during one titration, found from its final reading minus its initial reading.
The volume of solution delivered from the burette to reach the end point.
Specification C5.1b, C5.1c, PAG 2, PAG 5, PAG 6 · Paper 1 (Foundation), Paper 2 (Foundation), Paper 3 (Higher), Paper 4 (Higher)
The volume of solution delivered from a burette during a titration.
Revise: Titration TechniquesRepeat accurate titrations until closely agreeing, or concordant, titres are obtained. Calculate a mean from concordant accurate results only. Their agreement suggests that the end-point has been judged reproducibly, although it does not prove that every measurement is free from systematic error.
The volume delivered from a burette during a titration, calculated from the final reading minus the initial reading.
The accurately measured volume delivered from a burette during a titration.
Paper 1 (Foundation), Paper 2 (Foundation), Paper 3 (Higher), Paper 4 (Higher)
The volume delivered from a burette to reach the end point of a titration.
Revise: Titration procedureAdd acid fairly quickly while well short of the rough titre, then slowly, drop by drop, as the end point approaches. Swirl throughout so each drop mixes with the alkali before judging the colour. Stop at the first colour change that persists after swirling.
The volume of solution delivered from a burette during a titration, found by subtracting its initial reading from its final reading.
The volume of solution delivered from a burette during a titration.
The volume delivered from a burette during a titration.
A titre is the final burette reading minus the initial reading, not necessarily the final reading itself.
Use closely agreeing titres for the mean; leave out the rough trial.
Calculate each titre as final burette reading minus initial burette reading. Use the mean of concordant titres, not the rough result.
