Question

question 15 of 28. several dyes were mixed together and dissolved in water. you need to determine which dyes are in the solution, but not separate the entire mixture. how can you separate out a small sample of the dyes for identification purposes, but not separate the entire mixture? a. by distilling the dyes b. by using chromatography c. by filtering the dyes d. by using oils to distill the dyes

Explanation:

Chromatography is a technique used to separate and identify dissolved substances in a mixture, which is suitable for determining and separating dyes in a small sample without affecting the entire mixture. Distillation (A, D) separates based on boiling points, not effective for dissolved dyes. Filtering (C) separates insoluble solids, which dyes are not here.

Answer:

B. By using chromatography
