This how it works covers Titration Method (Required Practical) 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 7 of 14 in this topic. Use this how it works to connect the idea to the wider topic before moving on to questions and flashcards.
⚙️ Titration Method (Required Practical)
- RINSE the burette with the solution you'll put in it (removes water)
- FILL the burette with acid (or alkali) of known concentration
- RECORD the initial burette reading (read bottom of meniscus)
- PIPETTE exactly 25.0 cm³ of alkali (or acid) into a conical flask
- ADD a few drops of indicator
- TITRATE — add from burette slowly, swirling constantly
- NEAR END POINT — add dropwise until permanent colour change
- RECORD final burette reading
- CALCULATE titre (final reading − initial reading)
- REPEAT until you get concordant results (within 0.10 cm³)
Practice questions for Titrations (HT)
What is the purpose of a titration?
Explain why the burette should be rinsed with the acid solution before filling it for a titration.
Quick recall flashcards
What is a titration?
A technique to find an unknown concentration by adding a solution of known concentration until the reaction is complete
You measure exactly how much was added
What are concordant results?
Titration results within 0.10 cm³ of each other
These are the reliable results used to calculate the mean
