A typical practical paper contains 2-3 experiments (e.g. titration + QA; speed of reaction + QA) and 1 planning question.

 

Topics to Revise (Theory)

 

Qualitative Analysis	Chemical Calculations
Acids & Bases	Salt Preparation
Redox	Metals
Speed of Reaction	Energy Changes
Methods of Purification

 

Types of Experiments

• Titration (Acid-base/ Redox/ Iodometric)
• Calorimetry (Thermometric Titration)
• Qualitative analysis
• Speed of reaction (Clock/ Volume of Gas)

 

Planning Question

• Planning question requires students to describe an experimental procedure to achieve the objective(s) set.
• In the procedure, the apparatus for each measurement must be clearly stated. A diagram (labelled) may be drawn to illustrate the experimental setup.
• For most questions, the data to be collected must be shown, followed by a discussion of how the data can be processed to achieve the objective(s).
• For questions where a conclusion is needed, the conclusion must directly address the objective set.
