Adsorption is the phenomenon of attracting and retaining the molecules of a substance on the surface of a solid resulting into a higher concentration on the surface than in the bulk. The substance adsorbed is known as adsorbate and the substance on which adsorption takes place is called adsorbent. In physisorption adsorbate is held to the adsorbent by weak van der Waals forces and in chemisorption by strong chemical bond.

The answer is 3. Eye Lotion.

Argyrol is a medical preparation that contains silver protein, which is a mild antiseptic. It was once used as a treatment for a variety of eye infections, including gonorrhea, conjunctivitis, and trachoma. However, it is no longer widely used as an eye medication because it can cause argyrosis, a condition in which the silver in the argyrol deposits in the tissues of the eye, causing them to turn a bluish-gray color.

Argyrol is also not used to treat Kalaazar, stomach disorders, or for intramuscular injection.
