Question
- A. The formulation becomes a pure substance
- B. The formulation may not work as intended
- C. The formulation will always be more effective
- D. The formulation will change its state
Answer
The correct answer is The formulation may not work as intended. It matches formulation because the evidence is designed mixture composition and the expected result is useful product properties.
Explanation
The correct option is The formulation may not work as intended. 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 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.
