Below are sample questions representative of the exercises included on this worksheet and related 11.129 Chromatography and Separation Techniques skill assessments:

Problem 1Difficulty: Mastery

An environmental water sample contains trace organic pollutants with different polarities at very low concentrations. Which workflow best matches separation by affinity and practical analysis?

AUse coarse filtration only, because dissolved pollutants are large particles.

BUse simple distillation only, because trace pollutants always boil before water.

CUse a magnet, because polarity and magnetism are the same property.

DConcentrate pollutants by solid-phase extraction, then analyze them by liquid chromatography.

Solution & Explanation:Trace dissolved organics are not removed well by coarse filtration, and distillation may be inefficient or inappropriate. Solid-phase extraction can concentrate analytes by affinity, and liquid chromatography can separate them by interactions with phases.

Problem 2Difficulty: Mastery

A chromatogram has two well-separated peaks. Peak A appears at 2.0 minutes with small area; Peak B appears at 6.0 minutes with large area. Which statement is best?

APeak A must be more abundant because it appears first.

BPeak B must have a lower boiling point in every chromatography method.

CPeak B likely represents more detector-responding material, while retention times help compare identities to standards.

DPeak areas cannot provide any quantitative information.

Solution & Explanation:Well-separated peak areas can be used to estimate relative amounts when detector response is considered. Retention time alone does not tell amount; it is mainly an identity clue.

Problem 3Difficulty: Mastery

Two liquids have nearly identical boiling points but one is much more polar than the other. Why might chromatography outperform distillation for this pair?

AChromatography separates only by boiling point, so it is identical to distillation.

BChromatography can exploit polarity and phase affinity differences even when boiling points are nearly the same.

CDistillation always separates liquids with identical boiling points completely.

DFiltration through paper will separate any two liquids by polarity.

Solution & Explanation:Distillation depends mainly on volatility, so nearly identical boiling points are difficult. Chromatography can use differences in intermolecular attractions with stationary and mobile phases.
