WebPrepare 50 mL of 9:1 ligroin/acetone. 3. Open the stopcock and allow the liquid to become level with the upper layer of sand. Now your instructor will add about 2mL of the spinach pigment to your column. Load the spinach pigment onto the column by opening the stopcock. You should stop when the spinach pigment is level with the sand. WebThe solvent will dissolve the pigments of the Spinach when it begins to travel up the chromatography paper. The solvent moves upwards due to act of capillary action. Capillary action is when the hydrogen bonding in the solvent pulls the molecules upward and the hydrogen bonding between the chromatography paper helps defy gravity. top games cross platform with pc and ps4
