Product Name：Sodium Carbonate Molecular format：CH2Na2O4 CAS No：5968-11-6 Product molecular structure：   Chemical Properties:  Sodium carbonate is a white, almost white, or colorless inorganic salt, produced as crystalline powder or granules. It is hygroscopic and odorless with an alkaline taste.   Application: The most prominent characteristic of soda ash in solution is the high buffered pH response. For example, changing the sodium carbonate dosage from 0.03% to 30% only causes the solution pH to change from 10.5 to 11.7. Because of this, in mineral processing application, soda ash is used for pH control to a maximum value of 10.5.
