Question
Chapter 15, Problem 4Q
Interpretation Introduction
Interpretation:
In the green and yellow bands, the purity of the material, i.e., whether each band consists of a single component or not is to be explained.
Concept Introduction:
In the chromatography method, the components of the mixture areseparated based on the relative amounts of each component moving between a moving fluid stream, known as the mobile phase, and a stationary phase.
