Question
- A. A formulation is always a solid
- B. A formulation contains multiple components mixed together
- C. A formulation has a fixed composition
- D. A formulation cannot be used in products
Answer
The correct answer is A formulation contains multiple components mixed together. It matches formulation because the evidence is designed mixture composition and the expected result is useful product properties.
Explanation
The correct option is A formulation contains multiple components mixed together. This is correct because designed mixture composition is the evidence expected for formulation, and useful product properties is the result that supports the conclusion. Other options are weaker when they confuse gas tests, flame colours, ion-test precipitates, chromatography evidence, or pure-substance/formulation wording.
Common mistake
Misunderstanding Formulations
Students often confuse formulations with pure substances, thinking they are the same.
Remember that a formulation is a mixture designed for a specific purpose, while a pure substance is a single element or compound.
