Consider which phase remains still and which one moves.
3Question 3.
What is the primary goal of chromatography?
- To separate mixtures
- To analyze single compounds

Consider which chromatography type is effective for gases.
Question 5.
A laboratory has an unknown mixture containing three dyes. How would you use column chromatography to separate these dyes? Include the setup and observations you would expect.
Show hintHide hint
Think about how each dye interacts with the stationary phase.
Question 6.
Given a mixture of two volatile compounds, how would you determine which one has a higher affinity for the stationary phase in gas chromatography? Describe the process.
Show hintHide hint
Consider how gas chromatography operates and what affects retention time.
