While practical skills are assessed through written examinations, students are expected to develop hands-on laboratory skills through virtual methods. Students will:
- Conduct experiments to investigate chemical reactions and properties.
- Interpret data from practical investigations.
- Apply mathematical and analytical skills to solve chemistry problems.
- Develop skills in hypothesis testing, experimental design, and evaluation.
Suggested practical investigations include:
- Titration experiments – Determining acid/base concentrations.
- Electrolysis of solutions – Observing gas production.
- Reaction rate studies – Measuring the effect of temperature, concentration.
- Crystallisation and chromatography – Purification and separation techniques.
The course assesses students based on the following objectives:
