Soap molecules have non-polar and polar ends. When mixed with water, the soap dissolves, therefore having a physical change (but maintaining its chemical properties). The polar ends are in contact with water and consist of a salt, the non-polar ends are a long chain of hydrocarbons that do not mix with water.When soap molecules mix with water they form micelles, that consist of a bunch of molecules that in the center have the non-polar end (that traps dirt and other organic compounds) and in the exterior have the polar end in contact with water.
