Jun 27, 2018 · Sodium carbonate has a melting point of 1,564 ° F (851 ° C), a density of 2.53 g/cm 3, and is soluble in water. A water solution of soda ash has a basic pH and a strong alkaline taste. When it is placed in a slightly acidic solution, it decomposes and forms bubbles.
recompression crystallizers to precipitate sodium carbonate monohydrate (Na 2CO 3@H 2O). Impurities such as sodium chloride (NaCl) and sodium sulfate (Na 2SO 4)remain in solution. The crystals and liquor are centrifuged, and the recovered crystals are calcined again to remove remaining water.
The calcined material is combined with water to allow settling out or filtering of impurities such as shale, and is then concentrated by triple-effect evaporators and/or mechanical vapor recompression crystallizers to precipitate sodium carbonate monohydrate (Na2CO3 H2O).
