We don't know. It depends on the solute.


The dissolution of an ionic solid in water is manifestly a chemical change, in that strong electrostatic bonds have been broken, and new bonds generated in the new substances that have been formed.

On the other hand, the dissolution of say ethyl alcohol in water or petroleum ether is probably an example of physical change in that no new substances have been formed
