Introduction. I.A. Background. Soda ash is the common name for the technical grades of anhydrous sodium carbonat
21、e (Nazco,). Light and dense soda ash differ in physical characteristics only, such as density (weight of unit volume), angle of repose, and size and shape of particles. Light soda ash is a powder; dense soda ash is granular. Soda ash is an anhydrous material having a sodium carbonate content of more
22、 than 99 percent and a sodium oxide (Na20) equivalent of more than 57.9 percent. Sodium carbonate, although readily soluble in water, has the unusual characteristic of attaining maximum solubility at 95.7“F (35.4“C). At this temperature, 100 parts of water dissolve 49.7 parts of sodium carbonate. Th
23、e solubility of sodium carbonate decreases at temperatures above and below 95.7“F (35.4“C). I.B. History. The first edition of this standard for soda ash was prepared under the direction of the AWWA Water Purification Division. The standard was approved by the Executive Committee of the Water Purifi
24、cation Division and by the Water Works Practice Committee and received approval of the AWWA Board of Directors on July 1, 1949. Additional reviews resulted in an edited copy that was reaffirmed and approved as “Tentative“ by the AWWA Board of Directors on Oct. 15, 1951. The initial document was made
