In a chromatography experiment, how do you identify the components of an unknown mixture? Select one: Combine the mixture with a series of known compounds and observe the color of the dots. Combine the mixture with multiple known compounds and look for the largest spots. Compare the color of the mixture spots to the colors of pure known compounds. Compare the Rf values of the mixture components to the Rf values of pure known compounds.

Answer:

Compare the Rf values of the mixture components to the Rf values of pure known compounds.

Explanation:

In a chromatography experiment, how do you identify the components of an unknown mixture? Select one:

Combine the mixture with a series of known compounds and observe the color of the dots.

Combine the mixture with multiple known compounds and look for the largest spots.

Compare the color of the mixture spots to the colors of pure known compounds.

Compare the Rf values of the mixture components to the Rf values of pure known compounds.

In thin-layer chromatography, the retention factor (Rf) is used to compare and help identify compounds. The Rf value of a compound is equal to the distance traveled by the compound divided by the distance traveled by the solvent front (both measured from the origin).
