Question

question 3. a student has a dried spot of purple ink that contains a mixture of two different dyes whose properties are described in the table. substance form at r.t.p. solubility boiling point magnetism blue dye solid powder very soluble n/a not magnetic red dye solid powder slightly soluble n/a not magnetic the student wants to separate the dyes from each other. he decides to use chromatography with water as the solvent. part a. which of the substances is more soluble? part b. when the water soaks up the paper strip, part c. can chromatography be used to effectively

Explanation:

Step1: Analyze solubility data

From the table, blue - dye is very soluble and red - dye is slightly soluble in water. So blue dye is more soluble.

Step2: Understand chromatography principle

In chromatography, substances with higher solubility in the solvent move further up the paper strip. Since blue dye is more soluble, it will move further than the red dye when water soaks up the paper strip.

Step3: Determine chromatography effectiveness

Chromatography can be used effectively when there is a difference in solubility of the components of a mixture. Here, as blue dye is more soluble than red dye, chromatography can separate them.

Answer:

Part A: The blue dye is more soluble than the red dye.
Part B: The blue dye will move further up the paper strip than the red dye.
Part C: Yes, chromatography can be used effectively because the blue dye is more soluble than the red dye.
