Sodium chloride is a chemical compound not a change.
Sand is a mixture not a change.
Physical because you are not changing the substance.
Mixing sodium chloride and water is a physical change. The chemical composition of the sodium chloride (NaCl) remains the same in the solution, the sodium chloride molecules are simply dispersed in the water. The change is reversible and does not involve a chemical reaction.
