Prescribed Practical Work (IGCSE Edexcel)

The practical investigations in IGCSE Edexcel Chemistry are designed to help students develop their practical skills and understanding of chemical concepts. There are several core practical investigations that are recommended by Edexcel, which include:

Measuring the rate of reaction: This investigation involves measuring the rate of a chemical reaction by either monitoring the production of a gas, a change in colour or by measuring the mass of the reactants.

Investigating the effect of concentration on reaction rate: This practical involves studying how changing the concentration of a reactant affects the rate of reaction.

Investigating the effect of temperature on reaction rate: This investigation involves studying how changing the temperature of the reaction mixture affects the rate of reaction.

Identifying the ions present in an unknown salt: This practical involves using chemical tests to identify the positive and negative ions present in an unknown salt.

Investigating the electrolysis of copper chloride: This practical involves using electrolysis to separate copper and chlorine from copper chloride solution.

Investigating the properties of gases: This practical involves investigating the properties of gases such as pressure, volume, and temperature.

Investigating the enthalpy change of combustion: This practical involves measuring the heat energy released when a fuel is burned.

These are just a few examples of the practical investigations that students may be required to perform in IGCSE Edexcel Chemistry. The practical component of the course is an important aspect of learning chemistry as it helps students to develop their practical skills, apply their knowledge to real-world situations and reinforce their understanding of chemical concepts.
