This key facts covers Key Facts to Memorise 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 9 of 14 in this topic. Use this key facts to connect the idea to the wider topic before moving on to questions and flashcards.
📌 Key Facts to Memorise
- Titration = adding one solution to another to find an unknown concentration
- Burette measures the solution added (±0.05 cm³ precision)
- Pipette measures a fixed volume into the flask (e.g., 25.0 cm³)
- Indicator shows when reaction is complete (end point)
- Concordant results = titres within 0.10 cm³ of each other
- Calculate mean using only concordant results (ignore anomalies)
- Read burette from bottom of meniscus at eye level
- Key equation: n = c × V (V in dm³, so divide cm³ by 1000)
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
