Sodium carbonate manufacturing process, solvay process

Sodium carbonate manufacturing process, solvay process. Sodium carbonate (washing soda) is a white crystalline solid. It exists as a decahydrate ( Na 2 CO 3.10H 2 O) compound . Sodium carbonate is manufactured by solvay process in industrial scale and have very industrial and domestic uses.

Solvay process - Wikipedia

The Solvay process results in soda ash (predominantly sodium carbonate (Na2CO3)) from brine (as a source of sodium chloride (NaCl)) and from limestone (as a source of calcium carbonate (CaCO3)). The overall process is: 2 NaCl + CaCO3 → Na2CO3 + CaCl2The actual implementation of this global, overall reaction is intricate. A simplified description can be given using the four different, interacting chemical reactions illustrated in the figure. In the first step i…

Sodium carbonate - Wikipedia

Sodium carbonate, Na 2 C O 3, (also known as washing soda, soda ash and soda crystals) is the inorganic compound with the formula Na 2 CO 3 and its various hydrates. All forms are white, water-soluble salts that yield moderately alkaline solutions in water. Historically it was extracted from the ashes of plants growing in sodium-rich soils.
