Column Open: practical apparatus
What Column Open Is Used For
Column Open is practical apparatus for supporting separation or purification work. 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 column open to supporting separation or purification work, rather than only saying that it is used in a lab.

Common Trap
Do not describe apparatus by appearance only. Marks usually come from explaining its function in the practical method.
Column Packed: practical apparatus
What Column Packed Is Used For
Column Packed is practical apparatus for supporting separation or purification work. 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 column packed to supporting separation or purification work, rather than only saying that it is used in a lab.
