Dissolving sodium chloride in water is a physical change because the chemical composition of sodium chloride remains the same. The sodium and chloride ions are simply dispersed throughout the water, but they can still be recovered by evaporating the water.
Melting is a physical change because it does not change the chemical composition of the substance.
The dissolution of sodium chloride is considered as a chemical process.
