Adsorption is the accumulation of molecular species at the surface rather than in the bulk of a solid or liquid.

Two types of substances are involved in adsorption,

1. Adsorbent

2. Adsorbate

The molecular species or substance, which concentrates or accumulates at the surface is called adsorbate.

The material on the surface of which the adsorption takes place is called adsorbent.

Adsorption is a surface phenomenon.

So, Solids, particularly in finely divided state have large surface area and act as good adsorbents.

Examples: charcoal, silica gel, alumina gel, clay, etc.

Here, the oxalic acid get adsorbed on the surface of the activated charcoal.
\therefore

Adsorbate - Oxalic acid

Adsorbent - Activated Charcoal
