Soda ash dense granular is a water-soluble white granular that is alkaline (which makes the phenolphthalein solution lighter). High temperature can be decomposed, heated without decomposition.
Soda ash dense granular, true specific gravity 2.533(20ºC), bulk density 0.95 easily soluble in water, most solubility at 35.4ºC, the aqueous solution appears strong alkaliny. on exposure to air it will easily absorb moisture, carbon dioxide, and gradually to form sodium hydrogen carbonate and to form a cake.
