Product Details
High Quality Chinese Manufacturer supply 497-19-8 Sodium carbonate We provide high quality Sodium carbonate (CAS 497-19-8), at a very affordable prices to our customers.
Sodium carbonate is known as soda ash or washing soda and is a heavily used inorganic compound. Approximately 45 million tons of soda ash are produced globally both naturally and synthetically. Soda ash is obtained naturally primarily from the mineral trona, but it can also be obtained from nahcolite (NaHCO3) and salt brine deposits. Trona is a freshwater sodium carbonate-bicarbonate evaporite, with the formula Na3CO3HCO3 .2H2O. The largest known deposit of trona is located in the Green River area of Wyoming, and other large deposits are found in Egypt’s Nile Valley and California’s Searles basin around the city of Trona. Soda ash is produced from mined trona by crushing and screening the ore and then heating it. Th is produces a soda ash mixed with impurities. Pure soda ash is obtained by dissolving the product and precipitating impurities combined with filtering processes.
Sodium carbonate is also known as washing soda or carbonate of soda, sodium carbonate is a white crystal or powder made by converting salt into sodium sulfate, which was followed by roasting with limestone and coal. It is soluble in water and glycerin but not alcohol. Sodium carbonate was used as a pH modifier in toning baths and as the primary alkali in developers used for gelatin emulsions.
The CAS number of Sodium carbonate is 497-19-8.
