| Chemical Name： | Sodium Sesquicarbonate; Sodium Sesquicarbonate Dihydrate; Sodium Monohydrogendicarbonate |
| Molecular Formula: | Na2CO3·NaHCO3·2H2O |
| Molecular Weight: | 226.03 |
| CAS: | 533-96-0 |
| Shape & Properties： | Sodium sesquicarbonate is a chemical substance of white acicular crystal or flakded powder or crystalline powder, with the Relative Molecular Weight at 226.03 and the Relative Density at 2.112. It is not easy to be weathered, but easy to be dissolved in water. Its solubility in water is 13% at 0 ℃ and 42% at 100 ℃. The aqueous solution is alkaline, and its alkalinity is weaker than the alkalinity of sodium carbonate. It is prepared by mixing and crystallizing of the solutions of sodium carbonate and sodium bicarbonate in a certain proportion. |
| Uses： | 1. Used as food additives. 2. Used as the cleaning agent and protective agent for copper products. |
