Dissolution of salt in water is a [[1]]change.

When a salt is dissolved in water, it separates into its individual ions, indicating the formation of a brand-new material. There will either be a change in temperature, energy, the development of a gas, or the creation of precipitates because it is an irreversible process.

A chemical reaction is accompanied by a change in chemical properties. When a salt is dissolved in water it dissociates into ions. These ions are stabilized by polar nature of water. Consider the dissolution reaction of table salt given below;

$\mathrm{NaCl}\left(\mathrm{s}\right)\to {\mathrm{Na}}^{+}\left(\mathrm{aq}\right)+{\mathrm{Cl}}^{-}\left(\mathrm{aq}\right)$

The difference in electronic arrangement is resulting in a chemical change. Thus dissolution of salts in water is a chemical change.
