Rubber Stopper: practical apparatus
What Rubber Stopper Is Used For
Rubber Stopper is practical apparatus for collecting or measuring gas during practical work. 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 rubber stopper to collecting or measuring gas during practical work, rather than only saying that it is used in a lab.
