SURFACTANTES e TENSOATIVOS - Aprenda o que são e para que servem

Learn what surfactants or surfactants are and how they act. Amphiphilic or amphipathic molecules can reduce the surface tension of liquids. Surface tension is a physical effect that occurs at the interface of two phases, for example, the liquid phase and the gas phase. When we add a surfactant, also known as surfactants, these molecules are able to reduce the surface tension of liquids. A classic example of this effect of reducing the surface tension of liquids is the introduction of soap or detergent into water, causing it to become wetter. It's funny to say that water becomes wetter by adding surfactants, but that's what actually happens. It's even a pattern studied in chemistry, called wettability! Understand how this happens in this video lesson. Also watch the video about micellar water, an application of surfactants    • ÁGUA MICELAR? | Tudo sobre a QUÍMICA dos S...   Solved exercises from this class: Exercise 1 -    • Surfactantes | Exercício Resolvido | Unica...   (UNICAMP 2015) The sprays used in soccer matches have very varied formulations, but basically contain water, butane and a surfactant. When this mixture leaves the packaging, a white foam is formed that the referee uses to mark the players' positions. From a chemical point of view, this information suggests that the foam stabilized for a certain time is formed by small bubbles, whose films are made up of water and a) surfactant, which increases the surface tension of the water. b) butane, which increases the surface tension of the water. c) surfactant, which decreases the surface tension of the water. d) butane, which decreases the surface tension of the water.

The ionic part of surfactants interacts with polar substances, and the lipophilic part interacts with nonpolar substances.
