Soap suds are the bubbles formed when soap is mixed with water and agitated. These bubbles are created by the soap molecules trapping air, resulting in a frothy mixture. Soap suds are commonly seen when washing dishes, bathing, or cleaning surfaces. The presence of soap suds indicates that the soap is effectively working to lift dirt and grease. The suds help to encapsulate these particles, making them easier to rinse away. This property makes soap an essential cleaning agent in various applications, from household chores to industrial cleaning processes.
