Question
- A. To separate mixtures and identify substances
- B. To measure the temperature of substances
- C. To calculate the mass of substances
- D. To determine the pH of solutions
Answer
The correct answer is To separate mixtures and identify substances. It matches chromatography because the evidence is spot and solvent-front distances and the expected result is Rf or separation evidence.
Explanation
The correct option is To separate mixtures and identify substances. The answer stays inside Purity, formulations and chromatography by linking the observation to the conclusion instead of naming a substance without evidence. Other options are weaker when they confuse gas tests, flame colours, ion-test precipitates, chromatography evidence, or pure-substance/formulation wording.
Common mistake
Confusing Chromatography with Other Methods
Students often confuse chromatography with other separation methods like filtration or distillation.
Focus on the unique aspects of chromatography, such as the use of a stationary phase and a mobile phase for separating mixtures.
