sublimation from dry ice is a well-known phenomenon, which occurs at standard temperature and pressure. If water is accessible to the gaseous , it will dissolve in the water. Carbonic acid and bicarbonate ions form in the sequence of chemical equilibria: Dissociation of the carbonic acid causes the pH of the water to decrease.
