Light Soda Ash is a white, odorless, uniform product, which is free from dirt and other foreign matter. Soda Ash has a tendency to absorb moisture from the atmosphere. The moist Soda Ash then starts absorbing the atmospheric carbon dioxide. This phenomenon of absorption of moisture and carbon dioxide by Soda Ash is known as weathering. After weathering, Soda Ash is likely to contain appreciable moisture and sodium bicarbonate. However, the total alkali content of the bag does not change. Light Soda Ash has a tendency to cake when in contact with moisture and consequently becomes lumpy.
