Mixing salt and water is a physical change, not a chemical change. The salt does not change its chemical composition when it dissolves in water, only its physical state.
Solubilization of salt in water is a physical change.
Solubilization of salt in water is a physical change.
It is a physical change because the chemical composition of the salt and water does not change.

Yes, salt dissolving in water is a physical change because it does not involve a change in the chemical composition of the salt. The salt molecules are simply dispersed in the water, but they remain the same chemical substance.
Dissolving salt in water is a physical change- no chemical reaction took place. If the water evaporates, the salt is still there.
Dissolving in water is a physical change.
Dissolving in water is a physical change.
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.
