Answer:
Two important characteristics of the silica gel and alumina that are used for column chromatography-:
- Uniform particle size
- High specific area
Step-by-step 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.
