Answer:
Column chromatography uses Silica Gel
and stationary phase is Silica Gel
Explanation:
we know that silica get is amorphous and it is porous form of silicon dioxide.
Silica average pore size is 2.4 nano meters
that have strong affinity for water molecules and it is widely used as a desiccant
and voids may contain some liquids or may be filled by gas or vacuum
Silica gel is a drying agent so it remove moisture from an enclosed space
so that we found Silica gel packs in boxes containing electronics or new shoes and inside purses or medicine bottles.
and Silica gel is also used to dry the air in industrial compressed air systems
so Column chromatography uses Silica Gel and stationary phase is Silica Gel
