What is the role of surfactants in surface chemistry?

Step 1: Understand what surfactants are. Surfactants are substances that reduce the surface tension of liquids.
Step 2: Learn about surface tension. Surface tension is the force that makes the surface of a liquid behave like a stretched elastic sheet.
Step 3: Know where surfactants act. Surfactants accumulate at the interface between two phases, like liquid and air.
Step 4: See how surfactants work. When surfactants gather at the surface, they disrupt the cohesive forces between liquid molecules.
Step 5: Recognize the effect of surfactants. By reducing surface tension, surfactants help liquids spread and wet surfaces more easily.
