A chemist started to carry out column chromatography on aFriday afternoon, reached the point at which the two compoundsbegin separated were about three-fourth of the way down the column,and then returned on Monday to find that the compounds came off the column as a mixture. Speculate the reason for this. The column hadnot run dry over the weekend.
