What will happen to the surface tension of water droplets when a surface-active agent is added?

Question

Quizplus · Accepted Answer

Surface tension is the force exerted by like molecules at the liquid's surface. The introduction of a surface-active agent (e.g., soap) would decrease the cohesive forces between the water droplets, thus reducing their surface tension at the surface. With liquids (e.g., water), surface tension can be made to increase or decrease, but it cannot be eliminated.
