Question

What are two important characteristics of the silica gel and alumina that are used for column chromatography

Answer 1

Answer:

Two important characteristics of the silica gel and alumina that are used for column chromatography-:

• Uniform particle size
• High specific area                                                                        

Explanation:

The adsorbent must be thinly split in column chromatography to provide a well packed column that serves as a stationary step.  

The silica gel and alumina qualities that render them appropriate as column chromatography adsorbents are-:  

• Have a uniform particle size that guarantees uniform column packaging.  

• A highly specific area in which a rapid balance is formed between the mobile phase and the stationary phase.
