Question

A beverage company has a top selling energy drink, Jitters, which consists of only water, caffeine and Red Dye #5. They have decided to reformulate Jitters by adding glycerol to the old Jitters. Glycerol is a compound made of carbon, hydrogen, and oxygen. If the beverage company injected glycerol, the old form of Jitters, and the new form of Jitters into a high performance liquid chromatography instrument how many peaks would the beverage company see for each of the three different samples? Classify each substance (glycerol, old Jitters and new Jitters) as a pure substance or as a mixture.

Explanation / Answer

The high performance liquid chromatographic (HPLC) analysis of the two samples,

Old form of Jittlers : having water, caffeine and Red Dye #5 would show three peaks in the HPLC analysis, each corressponding to water, caffeine and Red Dye #5.

New form of Jittlers : having additional glycerol added to old form Jittlers, now would show four peaks instead of only three. The extra peak in the high performance liquid chromatogram comes from glycerol.

Glycerol : Is a pure substance

Old form of Jittlers and New form of Jittlers are both examples of mixture of substances.
