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.

Is mixing flour and salt a physical or chemical change?
physical
How is a salt water mixture a physical change?
A saltwater mixture is a physical change because it involves no chemical reactions. When salt dissolves in water, the salt molecules are simply dispersed throughout the water molecules without forming new substances. This change can be reversed by evaporating the water, leaving behind the salt crystals.
Is drinking milk a chemical change?
Distilling water is a physical change. When water is distilled, any trace impurities will left in the container it was distilled from. These impurities were not chemically bonded to the water, instead, they formed a mixture with the water, and a mixture is always created physically.
Is spilling water a chemical change?
No, spilling water is a physical change, not a chemical change. A chemical change involves a change in the chemical composition of a substance, whereas spilling water only changes its location and physical state.
Is concrete hardening an example of chemical or physical change?
Concrete hardening is an example of a chemical change. When water is added to the cement mixture, a chemical reaction occurs between the water and the cement particles, resulting in a new substance with different properties than the original components.
Is the Mixture of water and milk a physical change?

What is making salt water to gargle for a sore throat a physical or chemical change?
Physical. It is a mixture of salt and water. No chemical change has taken place.
Is dissolving air in water a chemical change?
It is a physical change, and now you have a mixture (or solution). No chemical reactions took place to make this change.
Is water a pure substance if it is mixed with something?
Only if the mixture is a physical, not chemical, change.

Is adding ice tea mixture to water a chemical or physical change?
Physical, because you are only diluting the tea, but not creating a new substance.
