a. name the technique that you would use to separate and identify the components of the solution.
b. provide specific details of the method used.
c. state the advantage of the method you choose.

A. you can separate the components through chromatographic techniques (GC or HPLC). The advatage of using a high-tech chromatography equipment is the simultaneous separation - contents analysis. 

b. chromatography is an affinity based separation which means using specific adsorbents, it can separate the component with a higher affinity to the adsorbents.

c. the advantage of which is the precision as well as the simultaneous separation and contents analysis.
