There is no well defined border between physical and chemical changes, so sometimes trying to classify a process as one or another is quite tricky. Solubility is often treated as physical change, even if many processes taking place during dissolution - like dissociation, hydration of ions, creation of hydrogen bonds with water molecules - are chemical in nature.

I would say that solubility is a process which apply to a physical chemistry.
