Question
- A. Gold
- B. Water
- C. Paint
- D. Oxygen
Answer
The correct answer is Paint. It matches formulation because the evidence is designed mixture composition and the expected result is useful product properties.
Explanation
The correct option is Paint. 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 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.
