Properties

Soda is hygroscopic. When stored for longer periods CO₂ and water may be absorbed depending on ambient conditions (increase in weight of up to 17 %).In aqueous solution soda is strongly alkaline. When anhydrous soda is dissolved heat is liberated. In contrast, when a concentrated solution of soda is diluted with water heat is taken up and the solution cools down.
