Question

The substance which can be used as adsorbent in column chromatography is:

• A. $N{a}_{2}O$
• B. $N{a}_{2}S{O}_4$
• C. $A{l}_2{O}_3$
• D. NaCl

Answer 1

The correct option is C $A{l}_2{O}_3$

The most commonly used adsorbent in column chromatography is $A{l}_2{O}_3$ and silica gel because these have high surface area and porous in nature such that they absorb substances onto the surface by inter-molecular forces.
