- The best choice of mobile phase in a thin layer chromatography experiments is: Group of answer choices The most volatile solvent possible. The least polar solvent possible. The most polar solvent possible. A mixture of solvents that takes into consideration the polarity of the analyte.arrow_forwardPlease don't provide handwritten solution ......arrow_forwardI have a question with the answer but I don't really understand it. Can you please explain the logic in this question & answer? For example, the hormone estradiolhas a partition coefficient of 3.2 between 1-octanol and water. How many extractions would need to be completed to recover > 99% from 250 mL of saturated solution using 100 mL of 1-octanol per extraction? The variables given are listed below along with the solution. In this scenario, it would require 5 extractions to recover > 99% of estradiol! Typically extractions are carried out only 2 or 3 times because the partition coefficient is usually larger than 3.2 and there are equal amounts of organic solvent and the aqueous layer.arrow_forward
