The molecule of sodium chloride remain unchanged.
Physical
A simple example is any substance which is soluble in a liquid. If you dissolve salt (sodium chloride) in water it will undergo a physical change. If you then evaporate the water the salt will reappear. All substances are capable of undergoing a physical or chemical change. If you heat salt it will become liquid, a physical change, if you then pass an electrical current through it it will break down into sodium and chlorine, a chemical change.
Solubilization of salt in water is a physical change.
Solubilization of salt in water is a physical change.
Assuming you're talking about salt forming as water evaporates: yes, that is a physical change. If you mean salt crystals forming from the combination of sodium and chlorine, then that's a chemical change.
it is a physical change. when salt and water is mixed . salt dissolves in water. here salt is not disappearing anywhere. its state is changing. chemical change means , once its reacted it cannot be regained . but here even though it is dissolved through evaporation we can regain the dissolved salt. its just a physical change.

physical
It is a physical change because salt is not changed chemically.
Dissolving salt in water is an example of a physical change. Although the ions of sodium and chlorine separate when the salt dissolves, no chemical reaction takes place.
This is a physical change.
