Questions & Step-by-Step Solutions

Which of the following is NOT a characteristic of adsorption?
  • Step 1: Understand what adsorption means. Adsorption is when molecules stick to the surface of a solid or liquid.
  • Step 2: Know that adsorption happens only on the surface, not inside the material.
  • Step 3: Compare adsorption with absorption. Absorption is when a substance is taken in and spreads throughout the whole material.
  • Step 4: Identify characteristics of adsorption, such as it being a surface phenomenon and involving weak forces like van der Waals forces.
  • Step 5: Determine which option does not fit the characteristics of adsorption.
