  • Kiriyama Funnel Reverse: practical apparatus

    What Kiriyama Funnel Reverse Is Used For

    Kiriyama Funnel Reverse is practical apparatus for supporting filtration and separation of insoluble solids. In A-level 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 kiriyama funnel reverse to supporting filtration and separation of insoluble solids, rather than only saying that it is used in a lab.

    Primary private mapping: AQA GCSE chemistry 8462, A simple model of the atom, symbols, relative atomic mass, electronic charge and isotopes.

    Common Trap

    Do not describe apparatus by appearance only. Marks usually come from explaining its function in the practical method.

  • Liebig Condenser: practical apparatus

    What Liebig Condenser Is Used For

    Liebig Condenser is practical apparatus for heating, cooling, or collecting substances during distillation. In GCSE Chemistry, the annotated diagram helps connect the apparatus to the method, measurement, or observation being tested.
