It is a chemical reaction for not only has the state changed of NaOH, but the identity of the substances have also changed.
NaOH + H2O --> Na+ + OH-
The "H2O" is not a reactant. It's actually supposed to go over the arrow. Sorry.
Nonetheless, the dissolution of NaOH will increase the Hydroxide concentration, thus making it more basic. It will not change the identity of H2O.
