Funnel: practical apparatus
What Funnel Is Used For
Funnel is practical apparatus for supporting filtration and separation of insoluble solids. 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 funnel to supporting filtration and separation of insoluble solids, rather than only saying that it is used in a lab.
