ANSWER:

Step 1 of 4

Paper chromatography is a simple but reliable method for separating a mixture into its constituent substances.

We are given a mixture of two vegetable dyes, one red and one blue, that we are trying to separate.

Two different chromatography procedures and the result of separations shown in the figure.

We need to find which procedure worked better and suggest a method to quantify how good or poor the separation was .
