Chromatography A widely used separation tool Purpose: Given a sample of unknown ink, we were to use chromatography paper to determine the identity of the sample. And also, we were to separate two dyes of different color using a silica gel column, made in lab. Procedure: Lab manual Experimental Chemistry pg.47-50. There were no changes made to this lab. Experimental measurements and Data: See attached page of results from the chromatography experiment. There was …showed first 75 words of 421 total…

In the silica gel separation, there was room for improvement in just establishing a silica gel column. It was difficult to determine how much glass wool we needed, with nothing to go by.
