Practical Work for IB Chemistry
Practical work is an important part of experimental sciences, and as such, it will make up a significant part of the course. The minimum requirement is 40 hours of practical work for SL and 60 hours for HL. Practical work may include simulations and modelling as well as traditional practicals. Although marks for individual practicals are no longer submitted to the IBO, all your work will be recorded on a form called the PSOW4.
There are now a small number of compulsory practicals that you need to complete (and to make sure that you understand). Your understanding of these could well be tested in paper 3. You have been warned . . .

The compulsory labs
- The obtaining and use of experimental data for deriving empirical formulas from reactions using mass changes
- Use of an experimental method of titration to calculate the concentration of a solution by reference to a standard solution
- Obtaining and the use of experimental values to calculate the molar mass of a gas from the ideal gas equation
- A calorimetry experiment for an enthalpy of a reaction should be covered and the results evaluated
- Candidate should have experience of acid base titrations with different indicators. Students should be familiar with the use of pH meters and universal indicator
- Performance of laboratory experiments involving a typical voltaic cell using two metal/metal ion half cells
- Construction of 3D models real or virtual of organic molecules
