Purity, formulations and chromatography
Question
- A. Because they are all pure substances
- B. Because each component contributes specific characteristics
- C. Because they are always in equal amounts
- D. Because they are designed to be impure
Answer
The correct answer is Because each component contributes specific characteristics. It matches formulation because the evidence is designed mixture composition and the expected result is useful product properties.
Explanation
The correct option is Because each component contributes specific characteristics. Use this as an exam check: if the observation is not useful product properties, the conclusion about formulation is not properly supported. 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.
