Purity, formulations and chromatography
Question
- A. To ensure the formulation is pure
- B. To achieve desired properties in the product
- C. To make the formulation cheaper
- D. To increase the volume of the product
Answer
The correct answer is To achieve desired properties in the product. It matches formulation because the evidence is designed mixture composition and the expected result is useful product properties.
Explanation
The correct option is To achieve desired properties in the product. This response is stronger than the distractors because it keeps the test, observation, and interpretation in the correct order for formulation. 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 think that formulations can be made with any random mixture of components without precise measurements.
Emphasize that formulations are specifically designed mixtures where components are mixed in carefully measured quantities to achieve desired properties.
