Burette: practical apparatus
What Burette Is Used For
Burette is practical apparatus for delivering accurate measured volumes during titration. In GCSE Chemistry, the annotated diagram helps connect the apparatus to the method, measurement, or observation being tested.
How To Use It In An Exam Answer
Use the marker labels to name the apparatus first, then say why it is suitable. A strong answer links burette to delivering accurate measured volumes during titration, rather than only saying that it is used in a lab.
