Used by AQA and Edexcel
Specification 5.8.1.2 · Paper 4
Revise: Chemical FormulationsA formulation is a mixture that has been designed as a useful product. Its components are deliberately chosen, and each has a particular purpose. Many formulations are complex mixtures containing several different chemicals.
Paper 5, Paper 6
One of the forces in chosen directions that together have the same effect as an original force.
Revise: Forces and vector diagramsResolving a force reverses the process of combining forces: one force is represented by two component forces in chosen directions, usually horizontal and vertical. The components together have the same effect as the original force; they are not extra forces acting alongside it.
When identifying a formulation, use the information given: link the deliberately chosen components and their measured quantities to the product’s required properties.
A formulation is a mixture, not a single compound. A controlled recipe does not mean its components are chemically bonded together.
You do not need to memorise the names of components in proprietary products.
