Stirrer Bar Round: practical apparatus
What Stirrer Bar Round Is Used For
Stirrer Bar Round is practical apparatus for supporting practical chemistry work. In GCSE or introductory practical science, 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 stirrer bar round to supporting practical chemistry work, rather than only saying that it is used in a lab.
