What kind of change occurs when salt dissolves in water chemical or physical?
Dissolution, meaning dissolving into a liquid form. It is a chemical reaction that begins with water covering a corner of the salt. The corner chlorine starts to leave the crystal and water bonds form. As the chlorine leaves more water molecules are left behind. The chlorine becomes fully solvated then the salt does the same.
