Question 1: (column chromatography) a. What effect on the chromatographic separation is expected if solvent level is below the adsorbent? b. Once the chromatographic column was prepared, why was it important to allow the level of the liquid in the column to drop to the level of the stationary phase before applying the solution of the compounds to be separated? c. Name two methods of carrying out the column chromatography technique? d. What are the two methods of packing a...
