Principle
Detergents reduce the surface tension of water. Their properties result from their molecular construction, with a long unpolar chain and a short, polar part. Explain how surface tension originates, the terms lipophilic, hydrophilic and the construction of other surface-active agents (tensides). Some specific reactions of the detergent stearic acid are examined in this experiment.
