Using paper chromatography, a Chem 16 student tried to separate the components  of an ink using 0.01% NaCl solution as mobile phase. His chromatogram is shown  in figure 1.  *rely on the picture* The student tried to identify whether component B can also be found in other pen  brands so with the same mobile phase, he ran a paper chromatography experiment  using brands X, Y, and Z. The results are shown in figure 2. A. Calculate the retention factors of components A, B, and C in figure 1. B. Arrange components A, B, and C in order of increasing polarity. C. From the results of his experiment, component B can also be found in which  brand/s?

SHOW CLEAR SOLUTION:

Using paper chromatography, a Chem 16 student tried to separate the components 
of an ink using 0.01% NaCl solution as mobile phase. His chromatogram is shown 
in figure 1. 

*rely on the picture*

The student tried to identify whether component B can also be found in other pen 
brands so with the same mobile phase, he ran a paper chromatography experiment 
using brands X, Y, and Z. The results are shown in figure 2.

A. Calculate the retention factors of components A, B, and C in figure 1.
B. Arrange components A, B, and C in order of increasing polarity.
C. From the results of his experiment, component B can also be found in which 
brand/s?
