What is the primary difference between adsorption and absorption?

Options

  1. AAdsorption occurs at the surface, while absorption is uniform throughout the bulk.
  2. BAdsorption is uniform throughout the bulk, while absorption occurs at the surface.
  3. CBoth occur only at the surface.
  4. DBoth occur uniformly throughout the bulk.

Correct answer

A. Adsorption occurs at the surface, while absorption is uniform throughout the bulk.

Step-by-step solution

The paragraph clearly states that in adsorption, the substance is concentrated only at the surface, while in absorption, the substance is uniformly distributed throughout the bulk.
