Even if the energetics are slightly endothermic the entropy effect can still allow the solution to form. If the other energetics of dissolution are favorable, this increase in entropy means that the conditions for solubility will always be met.There is an entropy change associated with the formation of a solution, an increase in entropy (randomness) that thermodynamically favors the solution over the two original states.Entropy can be thought of as the randomness or spread-outedness of a group of molecules.
