Formulations
Chemistry: AQA GCSE Higher, topic 8.1.2
Formulations
Formulations are mixtures of chemicals that have been designed to create useful products.
Each component has a role
- In a formulation, each component helps to decide what the mixture’s overall properties are.
Quantity of each component
- To make sure that a formulation does what it is supposed to, each chemical component must be present in a precisely measured quantity.
Examples of formulations
- Formulations are everywhere around us in day-to-day life. Examples include:
- Fuels
- Cleaning agents
- Metal alloys
- Fertilisers
- Medicines
Test yourself on Formulations
Choose the correct statement about formulations.
Why must each component of a formulation be present in a precisely measured quantity?
A cleaning agent formulation contains several chemicals mixed in exact quantities. What is most likely to happen if the quantity of one chemical is changed from its specified amount?
Choose the correct statement about formulation components in each pair.
Each component of a formulation helps decide its overall properties. If the amount of one chemical in a medicine formulation changed, what would most likely happen to the medicine?
