Questions & Step-by-Step Solutions
Which of the following statements is true about adsorption? (2023)
Step 1: Understand what adsorption means. Adsorption is when molecules stick to the surface of a solid or liquid.
Step 2: Identify where adsorption happens. It occurs at the interface, which is the boundary between two different phases, like solid and gas or liquid and solid.
Step 3: Recognize that adsorption is different from absorption. Absorption involves one substance being taken into the volume of another, while adsorption is only on the surface.
Step 4: Conclude that since adsorption happens at the surface, it is indeed a surface phenomenon.
