During silica gel chromatography, it is normal for: more polar compounds more polar compounds to elute more slowly than less polar compounds

It is a method in which a liquid serves as the mobile phase while the stationary phase is made up of solid adsorbents like silica gel and activated alumina powder. The adsorbents' activity and the solvent's polarity affect the active compound separation principle. A good separation of the compound occurs when the solvent's polarity is very low and the adsorbent's activity is strong and high. The outcomes of compound separation, on the other hand, are poor if the solvent's polarity is very strong and the activity of the adsorbents is high. It implies that chemical isolation and purification are not entirely pure.

The method of column chromatography is the most well-known and widely used method for separating complex mixtures that are packed in a column.
